In this guide
In bank exams, question selection decides results. Two candidates with the same knowledge can finish a prelims mock ten marks apart, because one spent seven minutes on a puzzle that never settled and the other spent those minutes on three easy questions at the end of the section. Nobody learns that from a book. You learn it from mocks, and only if you analyse them properly.
A mock taken and not analysed is mostly wasted. It tells you a score, which you already half-knew, and nothing about why. This guide is about using mocks as a diagnostic tool: when to take them, how many, and exactly what to do in the forty minutes after.
Types of mocks, and when to use each
| Type | What it is | When |
|---|---|---|
| Topic tests | 10–20 questions on one topic | While learning each topic |
| Sectional tests | One section, 20 minutes, timer on | From about month two |
| Full prelims mocks | 100 questions, three sectional timers | From about month three |
| Full mains mocks | All objective sections plus the descriptive | From a month before the mains |
| Previous-year papers | Memory-based papers from recent cycles | Throughout, to check the real level |
Topic tests teach. Sectional tests build speed. Full mocks teach selection and stamina. You need all three, in that order.
How many?
| Time before the exam | Prelims mocks | Mains mocks |
|---|---|---|
| 3 months | 1–2 a week | None yet; keep mains topics going |
| 2 months | 3 a week | 1 every two weeks |
| 1 month | 1 a day | 1 a week |
| After prelims | None | 2–3 a week |
These are ceilings, not targets. If you cannot analyse a mock properly, take fewer. Thirty mocks analysed well beat sixty taken and forgotten.
Exam-like conditions
- Same time of day as your likely slot.
- Full screen, no phone, no breaks, a rough sheet and pen as in the exam hall.
- Sectional timers on. Never pause a mock because a question is interesting.
- For mains mocks, do the descriptive at the end, typed, while tired. That is how it will feel on the day.
A 40-minute analysis
- Scores by section (2 minutes). Note them in your log, with accuracy.
- Wrong answers (10 minutes). For each, write why it was wrong: concept, calculation, misreading or guess.
- Skipped questions (10 minutes). Solve them now, untimed. Which were actually easy? This is usually where the biggest gains are.
- Time sinks (8 minutes). Which questions or sets took more than about two minutes? Were they worth it?
- Three actions (10 minutes). Write three specific changes for the next mock and add weak topics to your practice list.
Classify every error
| Error type | What it looks like | The fix |
|---|---|---|
| Concept | You did not know the method | Relearn the topic; do a topic test |
| Calculation | Right method, wrong arithmetic | Daily calculation drill; recheck the last step |
| Misreading | "Not" missed, units confused, wrong row read | Slow down on the question stem; underline mentally |
| Guess | No real basis, or only one option eliminated | Stop guessing below two eliminated options |
| Time | Correct later, but too slow in the exam | Practise the type under a timer |
After ten mocks, count the categories. If most errors are misreading or guesses, you do not need more study; you need calmer habits.
A worked analysis
Suppose, in one prelims mock, an aspirant's reasoning section went like this: 24 questions attempted, 20 right, 4 wrong. With reasoning at about 8/7 of a mark per question and a penalty of about 2/7:
- Score: (20 × 8/7) − (4 × 2/7) = 160/7 − 8/7 = 152/7 ≈ 21.71
The analysis finds:
- Two wrong answers came from one puzzle, where a clue was misread early.
- One wrong answer was a misread inequality.
- One was a guess with no option eliminated.
- Three skipped questions (a direction question, a coding question and a syllogism) turned out to be easy. The aspirant ran out of time because seven minutes went into a puzzle that was abandoned unsolved.
Now the "what if". Suppose those seven minutes had gone to the three easy questions, all answered correctly, and the blind guess had been skipped:
- Right: 20 + 3 = 23. Wrong: 4 − 1 = 3.
- Score: (23 × 8/7) − (3 × 2/7) = 184/7 − 6/7 = 178/7 ≈ 25.43
That is about 3.7 marks from the same knowledge, just better selection. Across three sections, gains like this decide whether a candidate clears.
Lessons mocks teach
- Which question types you should always attempt first.
- Which puzzle types you solve fastest (floor, box, linear or circular seating).
- Which DI formats suit you and which to leave.
- Where you over-invest time, and how long you can safely give a puzzle before moving on.
- How your accuracy changes when you push attempts.
A mock log
| Date | English | Quant | Reasoning | Total | Accuracy | Main lesson |
|---|---|---|---|---|---|---|
Add a column for your lowest section margin if you are tracking sectional cut-offs. Read the log every Sunday. Patterns show up over weeks, not in one mock.
Previous papers
- Memory-based papers from recent cycles show the real level and style.
- Solve them in timed conditions; they are often better calibration than an easy mock.
- Do not memorise them. Questions rarely repeat; question types do.
Choosing a mock series
- One main series is enough; add a second only for extra mains practice.
- Look for sectional timers, an interface close to the real exam, and detailed solutions.
- Prefer a series with many test-takers, so the percentile means something.
- Do not judge a series by whether it makes you feel good. An honest, slightly harder series prepares you better.
One wrong question, analysed properly
| Question | What happened | Real reason | Action |
|---|---|---|---|
| Quant Q14 (profit and loss) | Chose 25% instead of 20% | Took the profit on selling price, not cost price | Revise: profit % is on cost price unless stated otherwise |
Writing the real reason in one line is what turns a mock into learning. "Silly mistake" is not a reason.
When scores are low or flat
- Mock series differ in difficulty. Compare your percentile and your own trend, not raw marks.
- If scores are flat for two weeks, take fewer mocks and spend more time on analysis and weak topics.
- If one section drags your total down, switch to sectional tests in that section for a week.
- A bad mock close to the exam is information, not a verdict. Analyse it and move on.
What to do next
- Take your next mock at your likely exam time, with sectional timers on.
- Spend 40 minutes on the analysis steps above and classify every error.
- Start the mock log, and read it every Sunday.
- Use the prelims strategy to set a minute plan for each section, and apply it in the next mock.
