SBI PO Prelims vs Mains: What Changes Between the Two Stages

A common story in SBI PO preparation goes like this. A candidate clears prelims comfortably, spends the next few weeks doing more of what worked in prelims, and then finds the mains is a different exam. The same subjects appear, but the weights, the time per question, the type of reasoning and the role of English all shift.

This post is about that shift. It assumes you know the basics of the exam. For prelims tactics, see How to crack SBI PO prelims. For how SBI PO differs from IBPS PO, see IBPS PO vs SBI PO. If you are also writing IBPS PO, the IBPS PO prelims vs mains post covers that exam's version of this question.

The patterns below are as reported for the 2025 and 2026 SBI PO notifications. Coaching-site summaries disagree on some details, especially the descriptive paper, so read the notification on sbi.co.in/careers (also reachable at sbi.bank.in) before you fix your plan.

The stages in one view

	Prelims (Phase I)	Mains (Phase II)	Phase III
Purpose	Screening only	Decides most of the merit	Completes the merit
Counts in final merit	No	Yes	Yes
Duration	1 hour	3 hours objective, plus a descriptive test	Psychometric test, group exercise, interview
Questions	100	170 objective	Not applicable
Marks	100	200 objective, plus descriptive	50 (20 group exercise, 30 interview) as reported

SBI's recent notifications state that the psychometric test carries no marks but its findings may be placed before the interview panel. The final merit is drawn from the mains (objective plus descriptive) and Phase III, with the two converted to a fixed weightage. In recent cycles that has been widely reported as 75 for mains and 25 for Phase III; confirm it in your notification.

Prelims pattern

As reported for 2025 and 2026:

Section	Questions	Marks	Time
English Language	40	40	20 min
Quantitative Aptitude	30	30	20 min
Reasoning Ability	30	30	20 min
Total	100	100	60 min

Note what changed from older SBI PO patterns: English has 40 questions and quant and reasoning have 30 each. Older blogs and videos still show 30-35-35, which is the Clerk pattern and the older PO one.

Each wrong answer costs a quarter of a mark. Prelims marks are not carried forward.

Mains pattern

As reported for 2025 and 2026 (most summaries agree on this split; one widely read site lists Reasoning at 50 marks, so check):

Section	Questions	Marks	Time
Reasoning and Computer Aptitude	40	60	50 min
Data Analysis and Interpretation	30	60	45 min
General, Economy and Banking Awareness	60	60	45 min
English Language	40	20	40 min
Total	170	200	3 hours

Plus a descriptive test, typed, taken after the objective paper. For 2025 it was reported as 30 minutes and 50 marks, with tasks such as an email, a report, and situation analysis or precis writing. Some 2026 summaries describe a different number of tasks and marks. Since we could not confirm the 2026 split from the notification text itself, read it there.

What actually changes

1. English flips from heaviest to lightest

In prelims, English is the largest section, 40 marks out of 100. In mains it is 40 questions for only 20 marks, half a mark each. That is the single biggest change, and many candidates do not adjust to it.

What it means: in prelims, English is where you can build a lead. In mains, an English question is worth a quarter of a Reasoning or DI question by marks (half a mark against 1.5 or 2). Spend your mains preparation time accordingly. English still matters because of sectional performance and because the descriptive test depends on your writing, but it is not where mains merit is made.

2. Awareness appears, and it is big

Prelims has no awareness section. Mains has 60 questions for 60 marks, about 30 per cent of the objective total. A candidate who only started awareness after prelims has at most a few weeks to cover six to eight months of banking and economy news. That rarely works. Start it before prelims, at a lower intensity, and step it up afterwards. Our post on preparing banking awareness gives a weekly routine.

3. Quant becomes data analysis

Prelims quant is a speed test: simplification or approximation, number series, quadratic equations, a DI set, arithmetic word problems. Mains DI is 30 questions for 60 marks, two marks each, and is built on longer sets: caselets, mixed graphs, data sufficiency and arithmetic dressed as data. Calculation speed still helps, but reading the data correctly and setting up the problem matter more. See data interpretation tricks for set types.

4. Reasoning gets harder and gains computer aptitude

Prelims reasoning rewards picking the right two puzzles and finishing syllogisms and inequalities fast. Mains reasoning, at 1.5 marks per question on average, has longer puzzles with more variables, input-output, critical reasoning (assumptions, inferences, courses of action) and a few computer aptitude questions. A candidate who has only practised prelims-level puzzles will find mains puzzles slower than expected.

5. Time per question roughly doubles

Prelims: 100 questions in 60 minutes, about 36 seconds each. Mains: 170 questions in 180 minutes, a little over a minute each. The extra time is not a gift. It exists because each question is longer. Mains rewards stamina and steadiness over three hours, which you only build by sitting full-length mocks.

6. Writing enters the picture

The descriptive test is typed. It is checked, as in IBPS PO, for candidates who clear the objective part. Many candidates neglect it and then find that typing a clean, structured email and report in the time limit is harder than it looks. Practise it weekly once prelims is over, on a keyboard, with a timer. The IBPS PO descriptive post has a format you can adapt.

7. Then comes a test of the person

Phase III adds a psychometric test, a group exercise and an interview. Banking basics, your own profile and current economic news are all fair ground. The awareness work you did for mains pays again here.

A worked example: the same candidate in both stages

Here are made-up but realistic numbers to show the shift.

Prelims. English 32/40, Quant 19/30, Reasoning 21/30 (net scores after penalties). Total 72. A comfortable prelims with English carrying the score.

Mains, if the candidate changes nothing. English 28 correct, 4 wrong out of 40: net 28 x 0.5 minus 4 x 0.125 = 13.5 out of 20. DI 14 correct, 4 wrong: 28 minus 2 = 26 out of 60. Reasoning 18 correct, 6 wrong: 27 minus 2.25 = 24.75 out of 60. Awareness 30 correct, 10 wrong: 30 minus 2.5 = 27.5 out of 60. Total about 92 out of 200.

The English score, the strength in prelims, now adds only 13.5 marks. The candidate's 92 is pulled down by DI and awareness. Three extra correct DI questions are worth 6 marks; three more correct English questions are worth 1.5. That is the shift in one line.

(The penalties above assume a quarter of each question's marks; the notification states the rule.)

A plan for the gap between prelims and mains

In the 2026 cycle, mains was scheduled for September, a few weeks after prelims. That gap is short. A sensible split for it:

• Awareness: daily, the most hours of any section, finishing the backlog and revising.
• DI and reasoning: one mains-level set of each daily, timed.
• English: three or four short sessions a week, focused on reading comprehension and error types. See bank exam English errors.
• Descriptive: one timed, typed practice every few days.
• Full mains mocks: one or two a week, with an hour of analysis after each.

Measuring where you stand

A mains mock score means little without context: 95 out of 200 may be strong on a hard paper and weak on an easy one. Pareeksha's full mocks are fixed papers, so everyone in a cohort sits the same questions. If 5,000 students sat a paper and you finished 500th, you are at the 90th percentile of that group, regardless of how hard the paper was. Full mocks and PYQs are part of Pareeksha Pro; see pricing. The Daily Dangal is free and useful for daily awareness recall.

FAQ

Do SBI PO prelims marks count in the final selection? No. Prelims only shortlists candidates for mains. Final merit uses mains and Phase III.

Is there a sectional cut-off in SBI PO? SBI's approach to sectional qualifying marks has changed across cycles. Read the "qualifying marks" clause of your notification rather than relying on what a previous year's candidate tells you.

Why is English worth only 20 marks in mains? That is how SBI has structured the paper in recent cycles: 40 questions at half a mark each. It means English carries much less mains weight than in prelims.

When should I start the descriptive test? Read the format early, and begin timed typing practice as soon as your prelims is done. A few weeks of weekly practice is enough for most candidates if they actually do it.

Can I prepare for SBI PO and IBPS PO together? Yes. The syllabus overlaps heavily, though the patterns and calendars differ. See IBPS PO vs SBI PO.
