SSC CHSL (Combined Higher Secondary Level) recruits 10+2 pass candidates into posts like Lower Divisional Clerk/Junior Secretariat Assistant (LDC/JSA), Postal Assistant/Sorting Assistant, and Data Entry Operator (DEO). Tier-1 mirrors CGL's structure - 100 questions, 200 marks, 60 minutes, +2/−0.5 marking - across the same four sections. Tier-2 then adds a descriptive paper and, for DEO/certain posts, a typing or data-entry skill test that is itself a real hiring filter, not a formality.
Tier-1 is identical in structure to CGL's: 100 questions across General Intelligence, English Language, Quantitative Aptitude and General Awareness (25 each), 60 minutes, +2 for a correct answer and −0.5 for a wrong one. Where CHSL diverges is after Tier-1: Tier-2 is a single paper with a descriptive section (essay/letter/application, tests written English) alongside objective sections, and depending on the post you're eligible for, a Skill Test (typing speed for DEO posts, often 8,000 key depressions per hour) or a Typing Test (LDC/JSA, in English or Hindi) that candidates must clear to be considered - unlike CGL, where the equivalent skill component is narrower.
| Section (Tier-1) | Questions | Marks |
|---|---|---|
| General Intelligence | 25 | 50 |
| General Awareness | 25 | 50 |
| Quantitative Aptitude | 25 | 50 |
| English Language | 25 | 50 |
| Total | 100 | 200 |
The four sections cover broadly the same ground as CGL, calibrated to a 10+2 difficulty level rather than graduate level - expect slightly less depth in Quant (more arithmetic, less advanced algebra/trigonometry) and Reasoning built around classification, series, analogy, coding-decoding and simple puzzles. English leans on grammar fundamentals, one-word substitution, idioms, spotting errors and short comprehension passages. General Awareness draws on static GK and current affairs exactly like CGL, since both exams pull from the same pool of national-importance events, government schemes and science-in-the-news questions.
For Data Entry Operator posts, the Skill Test measures data entry speed, typically 8,000 key depressions per hour on a specified time window - this is scored strictly pass/fail and doesn't add to your Tier-1/Tier-2 marks, but failing it disqualifies you regardless of your written score. For LDC/JSA, the Typing Test requires a minimum words-per-minute in English or Hindi. Both need dedicated practice on the actual keyboard layout and software used at the test centre - written-exam prep alone will not get you through this stage.
Because Tier-1's difficulty is calibrated slightly lower than CGL's, the exam rewards consistency and speed more than depth - most aspirants who clear CHSL do so by minimising careless errors on questions they already know how to solve, not by mastering harder concepts. Pair full-length Tier-1 mocks (to build pace across all 100 questions in 60 minutes) with daily General Awareness revision, and if you're targeting DEO or LDC/JSA, start typing practice in parallel from day one rather than after Tier-1 - skill-test speed takes months to build, not weeks.

CGL is for graduate-level Group B/C posts; CHSL is for 10+2-level posts like LDC/JSA, Postal Assistant and DEO. Tier-1 patterns are structurally similar, but CHSL's overall difficulty is calibrated lower and includes a mandatory typing/skill test.
Yes, for Data Entry Operator posts the typing-speed skill test is a qualifying requirement - failing it means disqualification regardless of your written-exam score.
