Mathematics — Chapter-Wise Weightage
| Chapter | Expected Weightage |
|---|---|
| Sets, Logic + Matrices & Determinants | 4 |
| Trigonometric Functions | 8 |
| Pair of Straight Lines, Circle & Conics | 4 |
| Vectors | 9 |
| Three-Dimensional Geometry (Line & Plane) | 7 |
| Limits & Continuity | 0 |
| Differentiation | 7 |
| Applications of Derivatives | 7 |
| Indefinite Integration | 8 |
| Definite Integration & Applications | 4 |
| Differential Equations | 6 |
| Statistics | 0 |

Highest-priority Maths chapters: Vectors (9), Trigonometric Functions and Indefinite Integration (8 each), 3D Geometry, Differentiation and Applications of Derivatives (7 each) — these alone carry a huge chunk of the paper.
How to use this weightage smartly
- Start with the highest-weightage chapters in each subject — they give you the most marks per hour of study.
- Don’t fully skip low-weightage chapters. A “0” or low number here is a relative priority, not a guarantee those topics won’t appear — skim them so an easy question is never lost.
- Balance across subjects. In the PCM group, Mathematics carries double marks per question, so strong Maths can lift your overall percentile fast.
- Revise with MCQs, not just theory. MHT-CET is speed + accuracy. Practise chapter-wise MCQs and full tests.
- Track your accuracy per chapter and re-prioritise your weak, high-weightage chapters every week.
Frequently asked questions
Is this weightage official?
No. MHT-CET does not release an exact official chapter-wise mark split. This is an indicative guide built from recent-year trends to help you prioritise. Always cross-check with the latest official syllabus.
Which subject should I focus on most?
In the PCM group, Mathematics carries the most marks (2 per question), so improving Maths has the biggest impact on your score — but don’t neglect Physics and Chemistry, which are quicker to score in.
How much of MHT-CET is from Std 11 vs Std 12?
Roughly 20% from Std 11 and 80% from Std 12. Std 12 chapters (above) deserve the majority of your time, but keep Std 11 basics revised.
