Weekly December Mock Tests Schedule to Boost JEE Main 2026 Scores
Focusing on mocks in December with the right strategy and a month-long schedule can improve your score drastically.
- First week of December, focus on giving a full-length mock every day with post-mock analysis to improve the scores.
- Next 15 days, you can focus on subject-wise mocks while focusing on your weak chapters, and in the final week, return to full-length mocks.
- Totally target 14 - 16 full-length mock tests in December alone.
| Days(December) | Mock Focus | Duration | Post Mock Activity | Expected score boost |
|---|---|---|---|---|
| Dec 1- 7 | Full Syllabus (Session 1 simulation) | 3 Hours | Error log +50 PYQs revisit | +15 to 20 marks (Time Management) |
| Dec 8 - 14 | Physics/Chem Heavy (Boost weak subjects) | 3 Hours | Video solutions review | 10 to 15 marks (with conceptual clarity) |
| Dec 15 - 21 | Maths Intensive + Mixed | 3 Hours | Peer Discussion forum | 15 Marks (Accuracy in calculation) |
| Dec 22 - 31 | 4 full mocks + 1 light revision | 3 hours each | Weak topics drill | 10 marks (Exam temperament) |
| Total | 14 - 16 Mocks | - | Daily 2-hour analysis | +50 Marks Overall |

Ques. Are 14 - 16 mocks really enough in December? Won’t I need at least 20?
Ans. Multiple toppers say that: Quantity < Quality. 14 - 16 mocks with 100% analysis are better than 20 half-analysed ones. The magic is in the 2-hour analysis after each mock and not the mock count itself.
Ques. What if I’m very weak in 1 subject? Should I still follow this week-wise focus?
Ans. Yes, but tweak it accordingly. If you are weak in Physics, make weak 2 physics heavy. A user shared, “I did 4 Physics-heavy mocks in the first 15 days of Dec → Physics 28 → 68 in Session-1.”

Score Improvement Strategies for JEE Main 2026
- Deliberately experiment with the number of attempts with considering high accuracy, and taking risks by trying a larger number of questions. Attempting 85 questions with 88- 90% accuracy may hit 200 marks from 180 with the same difficulty level.
- Integrating PYQs in mocks, doing error analysis after every mock and simulating a full 3-hour JEE Main exam like mocks can increase scores by 50 marks.
When implemented together, the four strategies mentioned will provide a 50-mark score increase due to their combined effect.
Check:
| Strategy | Description | Expected gain | User Notes |
|---|---|---|---|
| Vary Attempts | Test 70 - 75 vs 80 - 85 vs 90+ questions per mock | +20 Marks (Optimised accuracy) | In 85 attempted Mock: Net score went from 180 → 200. |
| PYQ Integration | Solve 5 Must-do physics questions daily post mock. | +15 Marks (Pattern recognition) | 2024 PYQs boosted Physics from 40 to 55 |
| Error Analysis | Log mistakes by topic; revisit the next day | +10 Marks (Reducing silly errors) | Chemistry errors down 30% after 3 mocks |
| Time Management | Simulate a full 3-hour paper | +5 Marks (Stamina build) | Completed paper 10 min early in December mocks |
Ques. How do I practically “Vary attempts” in the same week?
Ans. Typically, you can follow this schedule
- Monday Mock: Attempt only 70 - 75 (with accuracy focus)
- Tuesday Mock: Attempt 80 - 85
- Sunday Mock: Go 90+ and see where accuracy breaks.
After 3 weeks, you will know your exact sweet spot (most find 83-87).

Ques. I already do error analysis, but I find no improvement in my scores.
Ans. You’re probably doing shallow analysis. Real analysis = rewrite the entire solution correctly in a separate notebook. Mark, why did you choose the wrong option, and where did you go wrong for each question, rather than just saying silly mistakes and moving on?

How to Analyse Every JEE Main Mock Test?
Just giving the mock test is not enough. 80% of the score improvement comes from analysis. Students who spend 4-5 hours analysing each JEE mock gain 8-12 marks per test.
- Noting chapter-wise marks, number of attempts, and the accuracy after each mock test helps you analyse your strengths. While marking questions you knew but did wrong can help you reduce silly mistakes, and can help you gain 10 to 15 marks.
- Analysing unattempted questions that you knew how to solve but couldn't, helps you understand time management.
| Step | Time Required | What to do | Expected Marks Gained |
|---|---|---|---|
| Scorecard | 10 min | Note chapter-wise marks, attempts and accuracy | - |
| Silly Mistakes | 30 min | Mark questions you knew but did wrong | +10 - 15 marks |
| Unattempted | 40 min | Solve all unattempted questions you could have done | +20 to 25 marks |
| New Concepts | 1 - 2 Hours | Note new formulas/tricks you saw in solutions | +10 marks |
| Step 5: Error log | 20 min | Maintain one notebook/sheet for repeated mistakes | +10 marks |

Ques. What’s the point of solving unattempted questions after the mock, when time was already over?
Ans. 90% of unattempted questions were actually solvable in very little time. After 8 - 10 mocks, you get trained to spot and solve them during the exam. Boosting your scores by 20 - 25 marks.
Ques. How do I stop repeating the same silly mistakes?
Ans. Maintain an error log notebook. Write question + exact reason (calculation error, misread, concept doubt). Revise the entire log every week.
Chapter-wise Weakness Tracker (Use this Table Every Week)
When you fix just 3-4 weak chapters through December JEE Main mocks, you gain 40-50 marks easily.
Here is a table with sample data given for your reference. Make this table and update it every Sunday or any day once a week.
| Subject | Weak Chapters | Marks Lost | Action Taken | Status after a Week |
|---|---|---|---|---|
| Physics | Rotation, NLM, Gravitation | 24 | 100 PYQs + 2 Mocks Focus | Strong |
| Chemistry | Organic Reaction Mech, p - p-block | 28 | GOC Map + Daily 20 Questions | Improved |
| Maths | Definite Integration, AOD | 32 | Solved Examples + Test | Now scoring 70+ |
Ques. If I feel 10 chapters are weak. How do I choose which ones to fix?
Ans. Any chapter where you’re scoring less than 50% in 3 consecutive mock tests = truly weak. Start with 3 - 4 weak chapters and fix the rest later.
