Pattern Shifts in JEE Advanced Exam Over the Years
The organising IITs have changed how marks are awarded and deducted. They made these changes to neutralise test-taking tricks and coaching-driven shortcuts.
- Numerical Answer Type (NAT): Earlier, answers were mostly single-digit integers (0–9). Since the shift to CBT, decimal answers rounded to two places have become common.
- Over 2022–2026, Mathematics was the toughest and most time-consuming section. It moved from clever shortcut problems to multi-step algebraic and calculus-heavy derivations.
- After syllabus updates in 2023–2024, questions on lab apparatus (vernier calipers, screw gauges, optical benches) and data or graph interpretation increased.
- Multiple-Correct Questions: Earlier, these followed all-or-nothing marking. They now offer partial marks for correctly selected subsets, with penalties for incorrect options.
- Earlier, matrix matching used 4×4 OMR formats. These were replaced by Match-the-List MCQs, while paragraph-based questions with shared data became part of the paper from 2021.
| Change | Earlier Format | Current Format |
|---|---|---|
| Numerical Value (NAT) | Single-digit integers (0–9) before 2018 | Decimal numericals to two decimal places, 25% to 35% of the paper, +4 and no negative marks |
| Multiple-Correct (MSQ) | All-or-nothing (+4 or −2) | Partial marking (+1, +2, or +3) with −1 or −2 for any wrong option |
| Matching | 4×4 Matrix-Match on OMR sheets | Match-the-List MCQs and 2-question Stem paragraphs (from 2021) |
| Marking scheme disclosure | Not in the brochure | Shown on screen 15 minutes before the exam |
Ques. What percentage of JEE Advanced is numerical value questions?
Ans. 25% to 35% of the paper by 2021–2026, typically +4 for correct and no negative marking.
Ques. What is the JEE Advanced chemistry weightage?
Ans. Physical about 35%, Organic about 35%, and Inorganic about 30% in the 2027 outlook.

How to Prepare for JEE Advanced Based on Chapter-Wise Weightage
Students can apply the below tips in their JEE Advanced preparation while keeping the chapter-wise weightage in mind:
- Cover the whole syllabus. High-weightage chapters anchor the schedule. JEE Advanced also blends low-weightage topics, such as Trigonometry or Mole Concept, into multi-concept questions.
- Target the high-return bridge chapters and practise Multiple-Correct and Numerical formats. Solve previous years' MSQ and decimal NAT questions from the top chapters.
- Link concepts across chapters. Solve mixed-topic worksheets and train for partial marking.
- Build precision for decimal numericals. Do not round intermediate steps. Answers need accuracy up to two decimal places.
