IIT JAM Preparation Guide

IIT JAM's three-section structure (MCQ, MSQ, NAT) means each part of the paper rewards a different skill — and only Section A actually penalises a wrong guess.

Exam Pattern

60 questions worth 100 marks in 3 hours, across three sections: Section A (30 MCQs, 50 marks, single correct option), Section B (10 MSQs — Multiple Select Questions, 20 marks, one or more correct options), and Section C (20 NAT — Numerical Answer Type, 30 marks, type in a numeric answer, no options). Negative marking applies only in Section A — 1/3rd mark for 1-mark questions, 2/3rd mark for 2-mark questions.

Preparation Strategy

Guess selectively in Section A only: It's the only section with negative marking — in Sections B and C, an unanswered question and a wrong attempt cost the same (zero), so there's no reason to leave a NAT or MSQ question blank if you have any idea.
Master NAT questions specifically: Section C rewards precise calculation over elimination strategies that work for MCQs — dedicated numerical-answer practice is different from typical MCQ prep and shouldn't be skipped.
Understand MSQ's all-or-nothing nature: Since there's no partial marking, an MSQ answer with even one incorrect selection scores zero — practise identifying all correct options confidently, not just one.
Choose your subject paper deliberately: Your JAM subject determines which PG programmes you're eligible for at which institutes — confirm target program eligibility before committing to a subject choice.
Practise past papers by section, not just full-length: Because each section tests a different skill (recognition vs. multi-select vs. computation), section-wise drilling builds each skill faster than repeated full mocks alone.
Time yourself at 3 minutes a question on average: 60 questions in 180 minutes is generous per question, but NAT and multi-step MCQs can eat disproportionate time — track your pacing across sections in practice.

Sectional Notes

Section A (MCQ) — Single correct answer from four options; negative marking applies.

Section B (MSQ) — One or more correct answers from four options; no negative or partial marking.

Section C (NAT) — Numeric answer typed directly, no options given; no negative marking.
