Solve 2023 to 2026 papers first - they reflect the current application-based style in Organic synthesis and Physical Chemistry NATs. Pre-2020 papers are useful for coverage but underestimate current difficulty.
IIT JAM Chemistry Exam Pattern and Marks Distribution 2026
The paper has three sections with different marking rules. Section A has negative marking; Sections B and C do not. This changes how aggressively you should attempt each section.
- Section A (50 marks): 30 MCQs - 10 of 1 mark (negative 1/3) and 20 of 2 marks (negative 2/3); one correct option per question
- Section B (20 marks): 10 MSQs of 2 marks each; no negative marking; select all correct options; no partial credit
- Section C (30 marks): 20 NAT questions - 10 of 1 mark and 10 of 2 marks; type the numerical answer; no negative marking
IIT JAM Chemistry Topic Wise Weightage - High Scoring Topics to Focus in Sample Papers
| Topic | Questions (approx.) | Difficulty | What to Watch For |
|---|---|---|---|
| Physical - Thermodynamics | 8-10 | Moderate-Hard | Gibbs energy, entropy, Hess's law applications |
| Organic - Reaction Mechanisms | 8-10 | Moderate-Hard | SN1/SN2, elimination, addition; multi-step synthesis |
| Inorganic - Coordination Chemistry | 6-8 | Moderate | CFSE, isomerism, magnetic moment, spectrochemical series |
| Physical - Chemical Kinetics | 4-6 | Moderate | Rate laws, Arrhenius equation, integrated rate expressions |
| Organic - Stereochemistry | 4-6 | Moderate | R/S assignment, enantiomers, diastereomers, optical activity |
| Physical - Electrochemistry | 4-5 | Moderate | Nernst equation, cell EMF, standard electrode potentials |
| Organic - Spectroscopy (IR/NMR) | 4-5 | Easy-Moderate | Characteristic IR absorptions, proton NMR chemical shifts |
| Inorganic - Chemical Bonding | 4-5 | Easy-Moderate | VSEPR, MO theory, hybridization, bond angles |
Do not skip Inorganic Main Group questions - they are usually the fastest in Section A. Coordination Chemistry appears in NATs too, so practice CFSE and magnetic moment numericals separately.

How to Use IIT JAM Chemistry Sample Papers to Get Top 500 AIR in First Attempt
Solving without a review system stops working after three to four papers. Here is how to get results from each one.
- Solve Section A first, then C, then B. This order keeps negative marking risk low while you are fresh.
- After each paper, sort wrong answers into three groups: topic gap, silly error, or new question type. Each needs a different fix.
- Track which topics produce the most wrong NAT answers - these are calculation process gaps, not content gaps.
- For Section B MSQ errors, note which distractors you fell for - they repeat across years.
IIT JAM Chemistry Section B MSQ and Section C NAT Strategy - The Skill That Separates Top 300 from Top 1000 AIR
Most students lose ranks in Sections B and C, not Section A. No negative marking means a completely different strategy, not an easier one.
- Section B: Attempt every question. Commit only when 80 percent confident in each option - one wrong option cancels the full 2 marks.
- Section C: Attempt all 20 questions. Do the 1-mark NATs first. Carry units through every step - most wrong NAT answers come from unit mismatch at the final step, not the wrong method.
- For Thermodynamics and Kinetics NATs, write the formula before substituting numbers - this eliminates most calculation errors.
IIT JAM Chemistry 4 Week Preparation Plan Using Sample Papers
- Week 1 - Solve the 2024 paper untimed. Note every question you could not start from scratch and list the specific formula or concept missing for each.
- Week 2 - Cover the three weakest topics from Week 1, then solve the 2023 paper under full 3-hour timing. Track your section-wise time split.
- Week 3 - Solve the 2022 and 2021 papers on separate days under exam timing. Check whether unit errors or method errors cause more wrong NAT answers.
- Week 4 - One full paper daily from 2019 to 2020 under exam timing. Stop new papers 2 days before your target date and review your error log only.
FAQs on IIT JAM Chemistry Sample Papers 2026
Ques. How many IIT JAM Chemistry sample papers are enough to get AIR below 500?
Ans. Ten to twelve full papers with a maintained error log is the benchmark. Solving 20 papers without reviewing mistakes rarely breaks AIR 1000.
Ques. Which section should I attempt first in IIT JAM Chemistry?
Ans. Section A first, then Section C, then Section B. Negative marking in Section A means you tackle it while freshest; Section B MSQs need the most careful evaluation and work best last.
Ques. Are IIT JAM Chemistry PYQ questions repeated in new papers?
Ans. Exact repetitions are rare, but Thermodynamics, stereochemistry, and CFSE calculations appear in almost every year. Five to seven years of PYQs covers most recurring areas.
Ques. Where can I download IIT JAM Chemistry 2025 question paper with answer key for free?
Ans. Collegedunia hosts IIT JAM Chemistry question papers from 2017 onward with official answer keys. The official IIT JAM website publishes response sheets and provisional answer keys within a week of the exam.
Ques. Is Section C NAT the easiest way to score marks in IIT JAM Chemistry?
Ans. Section C has the highest ceiling because there is no negative marking. But recent Physical Chemistry NATs require four to six calculation steps - strong formula application turns Section C into your scoring margin over the average student.
