Target 10–12 full-length mocks across the last 30 days, spaced so no two fall in the same weak chapter. After each one, spend a full day classifying every wrong answer as a concept gap, a silly error or a time problem, and log it in a mistake notebook you re-read daily in the final week. Five or six full mocks plus subject-length tests is a realistic version of the same thing.

Ten to twelve full-length papers in 30 days is one every two to three days, which is enough to see trends and few enough that you can actually analyse each one. The spacing is the point: two mocks back to back teaches you nothing new, and two a week is not enough to track movement.
| Window | Tests | What each one is for |
|---|---|---|
| Days 1–7 | 1 full mock (diagnostic) | Baseline score and subject-wise split before the revision sweep |
| Days 8–14 | 2 full mocks | Checking that your chapter-wise revision is converting into marks |
| Days 15–25 | 4–5 full mocks | The main block — alternate test day and analysis day |
| Days 26–30 | 1 full mock + 2 MAT sets | Final confidence check; no new material after it |
Each full mock must be sat under real conditions: 200 questions, 180 minutes, one sitting, no phone, no breaks, and an OMR sheet or a strict paper-only substitute so the bubbling time is included. A 200-question paper attempted in 150 minutes is not a mock — it is a different exam.
What Analysis Actually Means
After the paper, spend a full day on it. Go through every question you got wrong and every one you skipped, and put each into exactly one of three buckets. This classification is what makes the next mock different from the last one.
| Mistake type | What it looks like | The fix |
|---|---|---|
| Concept gap | You did not know the content at all | Re-study the chapter, then re-attempt its set. Highest cost, so it gets the most hours |
| Silly error | You knew it, misread the option or lost a negative | Re-read the question stem to the last word. Cheapest fix in the whole paper |
| Time problem | You knew it but ran out of clock, or rushed it | Timed practice on that block, plus a 60-second cut-off rule |
Most students find the same distribution twice: roughly half their losses are concept gaps, a third are silly errors and the rest are time problems. That distribution tells you where the next week goes — and it is usually not where students assume.
The Mistake Notebook
One notebook or notes file, one line per mistake, no paragraphs. The format that works is deliberately boring:
| Column | Example |
|---|---|
| Question number & topic | Q84 — plant hormones |
| What I answered | Gibberellin |
| Correct answer | Auxin (apical dominance) |
| Why I was wrong | Silly error — swapped two hormone functions |
| The rule to remember | Auxin = apical dominance; GA = stem elongation |
Re-read the whole notebook on days 26–30, once a day. Those lines are your real revision notes — far more useful than a chapter you read three times. A notebook with 60 honest lines is worth more in the final week than any new chapter.
How to Read Your Mock Scores
One total score tells you almost nothing. These four numbers do:
- Total score — trend over five mocks matters; one mock does not.
- Subject-wise split — compare against Biology 80, Chemistry 50, Physics 50, MAT 20 to see where you are losing relative to the paper.
- Accuracy vs attempted — 160 attempted at 70% is 112 marks; 190 attempted at 58% is 110. Attacking more questions only helps if accuracy holds.
- Time per block — where the clock actually went, against the per-block time budget.
Do not compare a mock score with a classmate’s. Their paper was a different set of 200 questions, and the only comparison that predicts anything is your own last five.
What to Do When a Mock Goes Badly
- Do not take the next mock immediately. Two bad papers in a row is a signal to analyse, not to test again.
- Find the bucket with the most entries. Five concept gaps in one subject means that subject gets the next three days, not that you need a new book.
- Fix three things per analysis day. A list of 40 fixes is a list of zero fixes.
- Watch the MAT separately. Twenty marks in fifteen minutes is a trainable skill, and it is the easiest block to improve late — see the MAT strategy guide.
Track the Practice That Counts
Mocks are where the score is, but chapters are where the marks are fixed. Practise the MECEE-BL chapters behind your weak subjects in the free app — one chapter-wise set at a time, with every attempt logged — and the per-chapter accuracy report tells you which gaps the mock analysis just confirmed. That is the loop: mock, analyse, fix the named chapters, mock again.
