SSC CHSL Tier-I Section-Wise Strategy and 60-Day Plan

For years, SSC CHSL Tier-I was a one-hour race where you could spend your time however you liked. The 2026 notice changes that. Each of the four sections now has its own 15-minute timer, and unused time does not carry forward. That single change makes your old strategy obsolete. You can no longer "finish Quant first and rush through English later". You must plan every section as a separate 15-minute exam.

This guide goes section by section. It covers the verified pattern from the official notice, the maths of negative marking, how to approach General Intelligence, English Language, Quantitative Aptitude and General Awareness, which topics to prioritise, realistic attempt targets, a 60-day plan and a mock schedule. It does not repeat the basics of eligibility and salary, which are covered in our main CHSL guide.

The 2026 cycle at a glance (from the official notice)

The Staff Selection Commission published the Combined Higher Secondary (10+2) Level Examination, 2026 notice on 7 September 2026. The points below come from that notice.

What changed: sectional timers and what it means

The Tier-I structure of 100 questions, 200 marks and 60 minutes is the same as before. The change is the sectional timer. According to the notice, the 60 minutes are divided into four fixed blocks of 15 minutes, one per subject. Coverage by coaching and news sites describes this as new for Tier-I, and Tier-II also has timers per section.

The notice lists the parts in this order: English Language, General Intelligence, Quantitative Aptitude, General Awareness, and marks the column "Not in sequence". So the order on your screen may differ. Practise in a way that does not depend on one fixed order. We could not confirm from the notice whether you can go back to a section after its timer ends. Assume you cannot, and read the instructions on your admit card and the mock interface at the exam centre.

What this means in practice:

• You get 36 seconds per question on average. 15 minutes divided by 25 questions is 0.6 minutes, or 36 seconds.
• Time is no longer shared. A strong section cannot lend time to a weak one. Fast sections like Reasoning and GK will leave minutes unused if you finish early, and those minutes are wasted.
• Each section needs its own exit rule. Decide a per-question cut-off, such as "if I have not started solving by 40 seconds, I skip".
• Review inside the section. Keep the last 60 to 90 seconds of every section for a quick review of marked questions.
• Weak-section damage is capped. A bad Quant block cannot eat into English any more, which is a small relief.

Tier-I is a shortlisting round: know what it decides

This is easy to miss. According to the notice, candidates are shortlisted for Tier-II on the basis of Tier-I performance, using normalised scores, and the final merit list is prepared on the basis of Tier-II marks (Sections I and II), subject to qualifying the computer knowledge test and the skill or typing test. So Tier-I gets you in the door. It does not decide your rank directly.

The notice also says there may be separate category-wise cut-offs for different posts (DEO/DEO Grade A in the specified departments, DEO/DEO Grade A elsewhere, and LDC/JSA). The actual cut-off for each cycle is decided after the exam. We do not quote past cut-offs here because we could not verify them from an official source. Check the result notice for the cut-off marks released each year.

The practical consequence: aim comfortably above the cut-off in Tier-I, but do not neglect the maths, reasoning and English foundations, because Tier-II tests the same subjects at a larger scale. Tier-II has 1 mark negative marking per wrong answer, which is harsher than Tier-I. A habit of accurate attempts built now pays off later.

The negative marking maths: when to guess

Each correct answer gives 2 marks and each wrong answer takes away 0.50 marks. So one wrong answer cancels out one quarter of a correct one. Four wrong answers cost you the value of one right answer.

• Blind guess among four options: expected value = (1/4 x 2) minus (3/4 x 0.5) = 0.5 minus 0.375 = +0.125 marks. Slightly positive, but tiny and risky.
• After eliminating one option (three left): (1/3 x 2) minus (2/3 x 0.5) = 0.667 minus 0.333 = +0.333 marks.
• After eliminating two options (two left): (1/2 x 2) minus (1/2 x 0.5) = 1 minus 0.25 = +0.75 marks.

The lesson is that educated guesses are worth it and blind guesses are break-even at best. Break-even accuracy is 20%: if your chance of being right on a question is above one in five, attempting it adds marks on average. In reality most blind guesses are right only about a quarter of the time, so the gain is small and swings are large. Use guesses when you can cut options, especially in English (where elimination is natural) and General Awareness (where partial knowledge is common).

The much bigger loss is not wrong answers but wasted time. A question that takes 90 seconds to solve costs you two other questions you could have answered at 36 seconds.

General Intelligence: the fastest marks in the paper

The notice says General Intelligence includes both verbal and non-verbal questions. Topics listed include analogy (semantic, number, figural), classification, series (number, letter, figural), coding-decoding, Venn diagrams, drawing inferences, embedded figures, paper folding and punched holes, word building, symbolic operations, space orientation, trends, critical thinking and social or emotional intelligence.

Approach. Reasoning is the section where speed is built by pattern recognition, not by formulas. Most aspirants who finish early in this section have simply seen a lot of question types. Aim to solve at 25 to 30 seconds per question so that the leftover time can go to review.

• Series and analogy: check the difference, then the ratio, then squares or cubes, then alternating patterns, in that order.
• Coding-decoding: write alphabet positions (A=1 to Z=26) and test the shift on the first letter only before extending it.
• Classification and odd-one-out: find the property shared by three items (parity, divisibility, category). For words, think about category before spelling.
• Venn diagrams and statements: draw the diagram. Do not try to solve in your head.
• Figure questions (folding, embedded figures, mirror/water image): these take longer. Solve them after the quick verbal ones.

Worked examples (General Intelligence)

Example 1: number series. 2, 6, 12, 20, 30, ? The differences are 4, 6, 8, 10, so the next difference is 12 and the answer is 42. Check: these are also n x (n+1) for n = 1 to 5, and the next term is 6 x 7 = 42.

Example 2: coding. If each letter of CAT is moved one step forward in the alphabet, the code is DBU (C to D, A to B, T to U).

Example 3: odd one out. 9, 16, 25, 36, 48. The first four are perfect squares (3, 4, 5 and 6 squared). 48 is not, so 48 is the odd one out.

Example 4: analogy. 5 : 125 :: 6 : ? The pattern is cube. 5 cubed is 125 and 6 cubed is 216.

Target (planning suggestion): attempt 22 to 25 questions with accuracy above 90%. This is the section where a high accuracy is realistic, so a skipped question here is a mistake only if the figure is genuinely too long.

English Language: accuracy over speed

The notice lists spot the error, fill in the blanks, synonyms and homonyms, antonyms, spellings, idioms and phrases, one word substitution, sentence improvement, active/passive voice, direct/indirect speech, sentence shuffling, cloze passage and comprehension passage. This is a basic-knowledge paper, and the notice says so explicitly in the part title.

Approach. English is rewarding because you can usually decide within 20 seconds whether you know an answer. Questions fall in two groups: knowledge questions (vocabulary, idioms, one word substitution), where you either know it or you do not, and rule questions (error spotting, voice, narration, fill in the blanks), where grammar rules give you the answer. Passage questions (cloze and comprehension) need reading time, so they get a fixed budget.

• Do the knowledge questions first. If you do not know a word, do not think. Eliminate and move on.
• Read the question before the passage. In comprehension, scan the questions first and read the passage for those answers only.
• For cloze passages, read the whole paragraph once, then fill the blanks that depend on grammar (tense, preposition, article) first.
• Build vocabulary daily. Ten words a day with one sentence each is enough. Revise the previous day's ten before starting new ones.

Worked examples (English)

Example 5: subject-verb agreement. "Neither of the two answers are correct." The subject is "neither", which is singular, so the correct form is "Neither of the two answers is correct."

Example 6: active to passive. "She writes a letter." The passive is "A letter is written by her." The tense stays the same (simple present) and the verb becomes "is written".

Example 7: direct to indirect. He said, "I am tired." In indirect speech, the reporting verb is in the past, so "am" becomes "was" and the pronoun shifts: He said that he was tired.

Example 8: articles. "He is an honest man." We use "an" because "honest" begins with a vowel sound (the h is silent). Compare "a university", where the first sound is "yoo", a consonant sound.

Target (planning suggestion): attempt 20 to 23 questions at 85% accuracy or better. Do not force the last two or three vocabulary questions you do not know.

Quantitative Aptitude: choose your questions

The notice calls this "Basic Arithmetic Skill", and the syllabus covers number systems, percentages, ratio and proportion, averages, simple and compound interest, profit and loss, discount, partnership, mixture and alligation, time and distance, time and work, basic algebra identities, geometry (triangles, circles), mensuration, basic trigonometry and heights and distances, and statistical charts (tables, bar, pie, histogram).

Approach. This is the section where selection of questions matters more than speed. With 36 seconds per question on average, some questions must take 20 seconds and a few can take 60. The skill is to recognise in five seconds which is which.

• First pass: one-step and two-step questions. Percentages, ratio, average, simplification, number series based on arithmetic, profit and loss and simple interest. These are the quick marks.
• Second pass: medium questions. Time and work, time and distance, mixture, mensuration formulas, algebra identities, data interpretation sets if they are short.
• Last: geometry with multiple steps and long calculation questions. Leave them unless time remains.
• Learn squares to 30, cubes to 15, tables to 20 and common fraction-percentage pairs (1/8 = 12.5%, 1/6 = 16.67%, 1/7 = 14.28%, and so on). This alone saves about 5 seconds per question.
• Use option-based checking. When options are far apart, estimate. When options are close, calculate fully.

Worked examples (Quantitative Aptitude)

Example 9: successive percentage change. A price rises by 20% and then falls by 20%. The multiplier is 1.2 x 0.8 = 0.96, so the net change is a 4% decrease (not zero).

Example 10: successive discounts. Discounts of 20% and 10% give a multiplier of 0.8 x 0.9 = 0.72. The single equivalent discount is 28%.

Example 11: ratio. Divide 160 in the ratio 3 : 5. Total parts = 8, one part = 20. The shares are 60 and 100.

Example 12: average. The average of five numbers is 24, so the sum is 120. A sixth number, 36, is added. The new sum is 156 and the new average is 156 / 6 = 26.

Example 13: time and work. A can finish a job in 12 days and B in 6 days. Together they do 1/12 + 1/6 = 1/12 + 2/12 = 3/12 = 1/4 of the job per day, so they take 4 days.

Example 14: speed and distance. A train 150 m long runs at 54 km/h. Convert: 54 x 5/18 = 15 m/s. Time to cross a pole = 150 / 15 = 10 seconds.

Example 15: simple interest. Rs 5,000 at 8% per year for 3 years: 5000 x 8 x 3 / 100 = Rs 1,200.

Example 16: compound interest. Rs 1,000 at 10% per year for 2 years: amount = 1000 x 1.1 x 1.1 = 1,210. Compound interest = Rs 210. (Simple interest would be Rs 200, so the difference is Rs 10, which equals the interest on the first year's interest.)

Example 17: profit percent. Cost price Rs 800, selling price Rs 920. Profit = 120. Profit % = 120 / 800 x 100 = 15%.

Example 18: algebra identity. If x + 1/x = 3, then x squared + 1/x squared = (x + 1/x) squared minus 2 = 9 minus 2 = 7.

Example 19: mixture. 20 litres of a mixture has milk and water in the ratio 3 : 2. Milk = 12 litres, water = 8 litres. Adding 4 litres of water makes water 12 litres in a 24-litre mixture, so the new ratio is 12 : 12 = 1 : 1.

Target (planning suggestion): attempt 17 to 20 questions at 80% accuracy or better. If Quant is your weak area, even 15 clean attempts is a good result. Do not chase 25.

General Awareness: the section of recall and revision

The notice says General Awareness tests awareness of the environment and its application to society, current events, everyday scientific observation, and matters relating to India and its neighbours, particularly history, culture, geography, the economic scene, general policy and scientific research. There is no fixed list of chapters, so you have to build coverage yourself.

Approach. GA is a 15-minute section where 25 questions can be done in 6 to 8 minutes if you know the answers. The rest of the time is not useful, since you cannot carry it to other sections. So here the plan is the opposite of Quant: attempt confidently what you know, and use elimination on the rest, instead of rushing.

• Static GK (the stable part): Indian polity (fundamental rights, parliament, constitutional bodies), history (modern India, freedom movement, ancient and medieval basics), geography (Indian rivers, states, climate, soils, resources), economy basics (banking, budget terms, RBI) and general science (physics, chemistry and biology at class 8 to 10 level).
• Current affairs: revise the last six months before the exam, focusing on awards, appointments, sports events, schemes, summits and important days.
• Science: NCERT-level science is the most reliable source of marks. Everyday science, such as human body, diseases, vitamins and basic reactions, comes up repeatedly.

Make short notes in four columns: topic, fact, source of confusion, date revised. Review them every week. For current affairs, one monthly capsule read twice is better than ten sources read once.

Target (planning suggestion): attempt 18 to 22 questions with 80% accuracy. For the questions you are unsure about, apply the elimination rule from the negative-marking section.

Topic priorities by section (a planning view)

We do not have an official count of how many questions come from each topic, so the list below is not a statistic. It is our planning judgement, based on the syllabus in the notice and on the way these topics fit into a 25-question block. Check the analysis of your own mock tests to refine it. Topics with high scope for quick marks come first.

Section	Study first (high return)	Study next	Study last
General Intelligence	Series, analogy, classification, coding-decoding	Venn diagrams, inferences, symbolic operations, direction and ranking	Paper folding, embedded figures, punched holes
English	Error spotting, fill in the blanks, synonyms and antonyms, idioms	Voice, narration, sentence improvement, cloze	Sentence shuffling, long comprehension passages
Quantitative Aptitude	Percentage, ratio, average, profit and loss, simple and compound interest, simplification	Time and work, time and distance, mixture, mensuration, algebra	Geometry with multiple steps, trigonometry, tricky data interpretation
General Awareness	Everyday science, polity basics, current affairs of recent months	Geography, modern history, economy basics	Ancient and medieval details, rarely asked trivia

Attempt targets: how the numbers add up

These are planning suggestions, not predictions and not cut-offs. They show how attempts and accuracy turn into marks under the 2 and minus 0.50 scheme. Replace the numbers with your own mock averages after your first few tests.

Section	Attempts	Correct	Wrong	Marks
General Intelligence	22	20	2	40 minus 1 = 39
English Language	21	18	3	36 minus 1.5 = 34.5
Quantitative Aptitude	18	15	3	30 minus 1.5 = 28.5
General Awareness	20	16	4	32 minus 2 = 30
Total	81	69	12	132

The minimum qualifying marks in the notice are 30% of 200 for UR, which is 60 marks, but the shortlisting cut-off is decided after the exam and is usually higher. Use your mock scores to judge your position, not this table.

Notice two things. First, even a decent performance leaves around 19 questions unattempted. Second, the 12 wrong answers cost only 6 marks, so a few errors are not a disaster, but they add up when accuracy drops below 75%.

Time split inside each 15-minute block

Section	Pass 1	Pass 2	Review
General Intelligence	9 minutes: all quick questions	4 minutes: figure questions	2 minutes
English	8 minutes: grammar and vocabulary	5 minutes: passages	2 minutes
Quantitative Aptitude	8 minutes: easy questions	5 minutes: medium questions	2 minutes
General Awareness	7 minutes: sure answers	5 minutes: elimination attempts	3 minutes

This is a starting template. After a few mocks, change it to match your strengths. For example, if you finish GA in seven minutes, use the extra minutes to double-check.

The 60-day plan

This plan assumes you can study 4 to 5 hours on a working day and a little more on weekends. If you study more, add extra practice, not extra topics. If you have fewer hours, stretch each phase and drop the "study last" topics from the table above.

Phase 1: Days 1 to 20 (foundation)

• Quant (1.5 hours daily): days 1 to 5 on percentages, ratio, average; days 6 to 10 on profit and loss, discount, interest; days 11 to 15 on time and work, time and distance; days 16 to 20 on mensuration, algebra and number system. Solve 30 to 40 questions per day on the topic.
• Reasoning (1 hour daily): series, analogy, classification and coding-decoding in the first ten days, then Venn, directions, ranking and inferences.
• English (1 hour daily): one grammar topic per day, plus ten vocabulary words. Cover articles, tenses, subject-verb agreement, prepositions, voice and narration.
• GA (45 minutes daily): polity and science chapters from school books, with notes. Start reading current affairs capsules.
• Mocks: one sectional test on day 10 and one on day 20, only for diagnosis.

Phase 2: Days 21 to 40 (speed and sectional practice)

• Switch from untimed practice to 15-minute sectional drills. Do one Quant or Reasoning drill every day, and alternate English and GA.
• Keep a mistake log with four columns: question type, why wrong (concept, calculation, time, guess), correct method, date to revisit.
• Study the "study next" topics. Revise the "study first" topics every third day.
• Geography, history and economy get 45 minutes daily. Science revision happens twice a week.
• Mocks: two full mocks a week from day 28, each followed by at least two hours of analysis.

Phase 3: Days 41 to 52 (full-length mocks)

• One full 60-minute mock every alternate day (six mocks in 12 days), with sectional timers on. Take it at the same time of day you expect to take the exam.
• On the other days, spend two hours on analysis and two hours on the weakest section.
• Do not start new topics. Only fill gaps shown by the mock analysis.
• Complete the GA revision cycle once. Revise the monthly current affairs capsules for the last six months.

Phase 4: Days 53 to 60 (revision and calm)

• One mock every two days (about three or four in total), the last one at least two days before the exam.
• Revise the mistake log, formula sheet, vocabulary list and GA notes.
• Sleep on time. The last 48 hours are for light revision, not for new questions.
• Check the admit card, the exam centre location and the documents you must carry. Check the latest notice for the exact date and shift.

If the exam date is announced for later than 60 days from now, stretch Phase 2 and Phase 3, not Phase 1. If it is earlier, compress Phase 1 to 12 days and remove the "study last" topics.

Mock test schedule and how to analyse them

Period	Full mocks	Sectional tests
Days 1 to 20	0	2 (diagnosis)
Days 21 to 40	4 to 6	10 to 12 daily 15-minute drills
Days 41 to 52	6	As needed for weak sections
Days 53 to 60	3 to 4	None, only revision

Total: about 13 to 16 full mocks in 60 days. More is not always better. A mock without analysis is a wasted mock. Use this analysis routine after every test:

1. Note your score and attempts per section. Compare with your target table.
2. Mark each wrong answer as concept gap, calculation slip, misread, time pressure or blind guess.
3. List questions you skipped but could have solved. These show the missed marks.
4. Re-solve every wrong and skipped question without looking at the solution first.
5. Add concept gaps to the revision list for the next three days.

Track three numbers across mocks: attempts per section, accuracy per section, and total score. If accuracy is falling while attempts rise, you are guessing too much. If accuracy is high and attempts are low, you are too careful and should increase speed on easy questions.

Common mistakes in Tier-I

• Treating the paper as one 60-minute block. With sectional timers, finishing a section early gains nothing. Practise in 15-minute blocks from the start.
• Spending a minute on one Quant question. Skip when you have not found a method in about 20 seconds.
• Blind guessing in the last minute. A guess with no elimination is barely positive on average. Use it only for questions where you have cut at least one option.
• Ignoring English because "I know English". The questions test rules, not fluency. Learn the rules.
• Reading current affairs only before the exam. Start in week one and revise monthly.
• Not reviewing mocks. Aspirants who take many mocks but analyse few do not improve.
• Skipping typing practice. Tier-II includes a typing or skill test for qualifying. Start light practice in the last two weeks of this plan, since it takes weeks to build speed.
• Not choosing a language for the questions. Practise in the language you will use in the exam, especially for reasoning and quant terms.
• Changing the strategy the day before. Go with what your mocks have shown works.

Beyond Tier-I: what comes next

The notice describes Tier-II as a computer-based test held in two sessions on the same day. Session I has Section I (Mathematical Abilities and Reasoning and General Intelligence, 30 questions each, 180 marks in total over one hour), Section II (English Language and Comprehension, 40 questions, and General Awareness, 20 questions, 180 marks over one hour) and Section III (Computer Knowledge Test, 15 questions, 45 marks, 15 minutes, qualifying). Session II has the skill test or typing test. Negative marking is 1 mark per wrong answer in Sections I, II and III. Typing standards for LDC/JSA are 35 words per minute in English or 30 in Hindi over 10 minutes. The DEO skill test is 8,000 key depressions per hour over 15 minutes. Candidates must qualify all sections. Read the notice for the full details.

So Tier-II is more of the same subjects, with a heavier penalty and larger sections. The foundation you build in the 60 days is not wasted.

Frequently asked questions

Is there negative marking in SSC CHSL Tier-I? Yes. The notice states 0.50 marks are deducted for each wrong answer. Unanswered questions carry no penalty.

How many questions and marks are there in Tier-I? There are 100 questions of 2 marks each, which makes 200 marks. Each of the four sections has 25 questions and 50 marks.

What is the time limit? 60 minutes in total, with a sectional timer of 15 minutes for each subject. Candidates eligible for a scribe get 80 minutes, with 20 minutes per subject.

Can I use unused time from one section in another? The sectional timers are designed so that each subject has its own 15 minutes. Plan on the basis that time does not carry over, and confirm the rules on the exam instruction screen.

Which section should I attempt first? The notice lists the subjects as "not in sequence", so the order on screen may vary. Practise being flexible. Within each section, solve easy questions first.

How many questions should I attempt to clear Tier-I? There is no fixed number. The cut-off is decided each year after the exam, and separate category-wise and post-wise cut-offs may apply. Use the target table as a planning guide and compare it with your mock scores, and check the latest result notice for cut-offs.

Does Tier-I decide my final rank? According to the notice, Tier-I is used to shortlist candidates for Tier-II. The final merit list is prepared on Tier-II marks (Sections I and II), subject to qualifying the computer test and the skill or typing test.

Is 60 days enough? For most candidates with some school-level preparation, yes, if the plan is followed daily and mocks are analysed. If your basics in maths are weak, spend more of the first phase on Quant.

Which section is the easiest to score in? For most aspirants, General Intelligence and English give the best return per hour. But it depends on your background. Use your first two sectional tests to find your own strongest section.

Where can I check the exam date? The notice says the Tier-I and Tier-II schedules are to be notified later. Check the official SSC website for the latest notice and your admit card for the final date, shift and centre.

Final word

The new sectional timers reward candidates who train the way the exam is run: four short, separate tests. Build each section's habits, track your numbers and fix your leaks one mock at a time. Practise with full-length mocks and sectional tests on Pareeksha under the same 15-minute timing, review each one carefully, and walk into the exam hall having already done it many times.
