A good JEE mock test strategy has three parts: the right mocks, a steady number each week, and a review of every lost mark. Skip the review, and the same marks go in every mock. This page shows how to pick mocks that match the 2027 paper, how many to take up to each session, and a 30-minute review that turns each mock into next week’s plan.
Pick · Take · Review in 30 minutes · Fix one type a week
30 + 20 = 50 marks lost
Quick answer
Which mocks: NTA’s own sample test first, to learn the screen. Then mocks that match the 2027 pattern.
How many: one full mock and one maths-only mock a week from mid-November, then two full mocks a week in the last weeks.
Review: within a day, in 30 minutes, with every lost mark given one of 6 mistake types.
What a mock must copy: the 2027 paper facts
A mock only helps if it is like the real paper. These are the rules from the JEE (Main) 2027 Information Bulletin.
| Fact | What NTA says | What to check in a mock |
|---|---|---|
| NTA practice | A sample or mock test will be on nta.ac.in for hands-on practice | Use it to learn the screen before other mocks |
| Paper | 3 hours, 75 questions, computer-based | Full length, on a screen, not on paper |
| Maths | 20 Section A questions with options and 5 Section B number questions, all compulsory | Not 10 Section B questions with 5 to choose. That is an old pattern. |
| Marks | +4 right, −1 wrong, in both sections | Minus marks in Section B too |
| Number answers | Rounded off to the nearest whole number, typed on an on-screen keypad | Practise rounding and the keypad |
| Session 1 | 20, 21, 22, 23, 24 and 28 January 2027 | Count your mock weeks back from here |
| Session 2 | 2 to 7 April 2027. The better NTA score of the two counts. | A second plan, after Session 1 |
| Shifts | 9:00 am to 12:00 noon, or 3:00 to 6:00 pm, India time | 7:30 to 10:30 am or 1:30 to 4:30 pm UAE time. Start full mocks then. |
The bulletin does not say how many NTA mock tests there will be, or when they go up. NTA’s site, nta.ac.in, could not be opened when we checked on 12 November 2026.
How many mocks, and when: a plan to Session 1 and 2
A full mock is all three subjects in 3 hours. A maths-only mock is the 25 maths questions alone, at the maths pace you plan for the real paper. This plan is our advice, not an NTA rule.
| Weeks | Full mocks | Maths-only mocks | Main job |
|---|---|---|---|
| 16 Nov to 13 Dec 2026 | 1 a week | 1 a week | Find your two most common mistake types |
| 14 Dec 2026 to 10 Jan 2027 | 1 or 2 a week | 1 a week | Fix one type each week |
| 11 Jan 2027 to your Session 1 day | 2 a week | None | No new topics. Last mock 2 days before your test. |
| After Session 1 to 28 Feb 2027 | 1 a week | 1 a week | Topics that cost marks in Session 1 |
| 1 Mar 2027 to your Session 2 day | 2 a week | None | Same as before Session 1 |
One rule beats any count: do not take a new mock until you have reviewed the last one. Two reviewed mocks teach more than four that were only scored.
Not finished all the topics? Still take mocks. Mark questions from topics you have not done as “not yet”, and leave them out of the review.
The 30-minute review: sort every lost mark
Do it the same day or the next day, while you still remember your thinking. Set a timer. Look only at maths here, and do the same for the other two subjects.
Minutes 0 to 5: list the lost marks. Write the number of every maths question that was wrong or blank. Add any right answer that took you more than 3 minutes.
Minutes 5 to 20: give each one a type. Use the table below. Choose one type for each question. If two fit, choose the first mistake you made.
Minutes 20 to 25: count. Add up the marks lost to each type. A wrong answer costs 5 marks against a right one. A blank costs 4.
Minutes 25 to 30: write one fix. Pick the type that cost the most marks. Write one fix for next week, from the next section.
| Type | How it looks in a mock |
|---|---|
| CNC: concept not clear | You could not start, or your method was wrong |
| DRC: did not read carefully | You answered a different question from the one asked |
| CWV: copied a wrong value | A number changed between the screen and your rough sheet |
| CMT: calculation mistake | Right method, wrong sum |
| BPT: bad presentation | Messy rough work, so you lost a sign or a line |
| ROT: ran out of time | Blank because you never reached it |
Keep each review on one page: question number, section, wrong or blank, marks lost, type, fix. After four reviews, the page shows a pattern that one score never does.
Free BMI Maths Test
Same marks lost every mock? Find the mistake type.
The 6 types above come from the Free BMI Maths Test. It sorts every mistake into CNC, DRC, CWV, CMT, BPT or ROT, and finds your child’s real maths level, so the fix goes to the real cause.
Turn the review into next week’s plan
Fix the type that cost the most marks first. One fix a week is enough. Then check in the next mock if that type’s count went down.
| Top type | Fix for next week |
|---|---|
| CNC | Go back to the topic. Do 15 untimed questions on it before the next mock. |
| DRC | Before you work, underline what the question asks for: the term, the sum, the least value. |
| CWV | After you copy the question to your rough sheet, check each number once against the screen. |
| CMT | 10 minutes of hand sums a day, and check each answer by putting it back in. |
| BPT | Split each rough sheet into boxes, one per question, with the question number on top. |
| ROT | Work on pace and skip rules. See JEE maths time management. |
A score that does not move is often one type that never got fixed. If wrong answers are the problem, the JEE Main marking scheme page shows when a guess is worth the risk.
For UAE families: what to do now
- Students: the Session 1 form closes on Sun 22 Nov 2026 at 10:20 pm UAE time. Take your first full mock in the week of 16 November.
- Students: keep every review page in one folder. Bring it to any session where you go over mocks.
- Parents: ask for the review page, not the score. A falling count for one mistake type is real progress, even when the score is flat.
- Parents: keep the mock mornings free. A 7:30 am start means sitting down by about 7:15 am.
- Both: for more practice questions, use our JEE-style maths questions with answers.
A mock question reviewed step by step
This is a practice question in the style of JEE Main. It is not a real past question.
Number answer: the sum of the first n terms of an arithmetic sequence is 3n² + 5n. Find the 10th term.
In the mock, the student typed 350. That cost −1.
Step 1, what went wrong: 350 is the sum of the first 10 terms: 3 × 100 + 5 × 10. The question asked for the 10th term. Type: DRC, did not read carefully.
Step 2, the right working: the 10th term is the sum of 10 terms minus the sum of 9 terms. That is 350 − (3 × 81 + 5 × 9) = 350 − 288 = 62.
Step 3, a check: the terms are 6n + 2, so the first term is 8 and the 10th is 62. Both ways agree, checked in Python.
Step 4, the fix: next week, underline “10th term” or “sum” in every sequence question before you start.
The made-up mock in numbers: 14 right, 6 wrong, 5 blank in maths.
Score: 14 × 4 − 6 = 50 out of 100. Lost: 6 × 5 = 30 marks from wrong answers and 5 × 4 = 20 from blanks.
The review tagged the 6 wrong answers as 3 CNC, 2 CMT and 1 DRC, and the 5 blanks as 4 ROT and 1 CNC. CNC cost 19 marks, ROT 16, CMT 10 and DRC 5. So the fix for next week is CNC: the topic behind those 4 questions.
Questions people ask about a JEE mock test strategy
How many JEE Main mock tests should I take?
NTA sets no number. Our plan gives 10 to 17 full mocks before Session 1, by your test day, plus maths-only mocks. More mocks without reviews do not help.
When should I start mocks?
For Session 1 in January 2027, start in mid-November 2026, even if some topics are not done. Leave those questions out of the review.
How do I analyse a JEE mock test?
In 30 minutes, within a day. List every lost mark, give each one of 6 mistake types, add up the marks lost to each type, and write one fix for the costliest type.
Are NTA mock tests free?
The JEE Main 2027 bulletin says a sample or mock test will be on nta.ac.in for hands-on practice. It does not mention a fee. We could not open nta.ac.in to check when we wrote this page.
Why is my mock score not going up?
Most often, the same mistake type comes back in every mock because it was never fixed. Sort your lost marks for three mocks and look for the type that keeps costing the most.
Mock scores stuck?
The Free BMI Maths Test finds your child’s real maths level and the reason for each mistake.
