JEE Advanced 2021 Question Papers and Answer Keys; Download PDF
JEE Advanced 2021, conducted by IIT Kharagpur on October 3, 2021 (Sunday), was held in Computer-Based Test (CBT) mode across multiple centers in India and abroad. JEE Advanced consisted of two compulsory papers, Paper 1 and Paper 2, each covering Physics, Chemistry, and Mathematics, followed by the AAT exam on 18 Oct, 2021.

JEE Advanced 2021 Exam Pattern and Marking Scheme
JEE Advanced 2021 was conducted in online mode with two compulsory papers held on the same day, testing Physics, Chemistry, and Mathematics through a mix of conceptual and application-based questions.
| Paper | Pattern Details |
|---|---|
| Paper 1 | MCQs (single & multiple correct), numerical value questions, match-type questions; negative marking in selected sections |
| Paper 2 | MCQs, numerical and comprehension-based questions; slightly different distribution and partial marking in some questions |
| Common Structure | Both papers included Physics, Chemistry, Mathematics with 3-hour duration each; compulsory attempt of both papers |
| Marking Scheme | +3 for correct single-correct MCQs, +4 for multi-correct questions, -1 negative marking in selected MCQs, no negative marking in numerical questions, partial marking in some sections |

JEE Advanced 2021 Paper Analysis
JEE Advanced 2021 showed a highly conceptual and unpredictable paper across years, where difficulty varied slightly between Paper 1 and Paper 2. Overall, the paper tested deep understanding, logical thinking, and multi-step problem solving rather than direct formula application.
| Subject | Difficulty Level | Key Observation |
|---|---|---|
| Mathematics | Moderate to Difficult | Lengthy calculations; topics like Calculus, Coordinate Geometry, and Vectors & 3D were dominant and time-consuming |
| Physics | Moderate to Difficult | Concept-heavy paper with questions from Mechanics, Electricity & Magnetism, and Modern Physics; multi-step numericals were common |
| Chemistry | Moderate | Balanced mix of Physical, Organic, and Inorganic Chemistry; more concept-based than memory-based, especially Coordination Compounds and Organic reaction mechanisms |
JEE Advanced 2021 Most Repeated Topics
JEE Advanced 2021 had questions from core high-weightage chapters, especially in Calculus (Math), Mechanics (Physics), and Organic Chemistry. While exact question numbers can vary slightly across Paper 1 and Paper 2 interpretations, the overall trend below reflects the most repeatedly tested areas across both papers.
| Subject | Topic | Approx. No. of Questions | Pattern Focus |
|---|---|---|---|
| Mathematics | Calculus (Limits, Derivatives, Integration, Area Under Curve) | 8–10 Questions | Multi-step numerical + application-based MCQs |
| Coordinate Geometry (Circle, Parabola, Ellipse, Hyperbola) | 4–6 Questions | Conceptual MCQs + mixed geometry problems | |
| Vectors & 3D Geometry | 3–5 Questions | 3D visualization + numerical-based questions | |
| Physics | Mechanics (Laws of Motion, Work-Energy, Rotation) | 7–9 Questions | Long numerical chains + conceptual MCQs |
| Electricity & Magnetism | 5–7 Questions | Circuit-based reasoning + formula application | |
| Modern Physics (Photoelectric Effect, Nuclear Physics) | 3–4 Questions | Direct conceptual + formula-based questions | |
| Chemistry | Organic Chemistry (Reaction Mechanisms, Hydrocarbons, Carbonyls) | 6–8 Questions | Mechanism-based MCQs + conceptual application |
| Coordination Compounds | 3–4 Questions | Theory + structure-based reasoning | |
| Chemical Bonding & Periodic Table | 3–5 Questions | Conceptual MCQs and trend-based questions | |
| Physical Chemistry (Thermodynamics, Equilibrium) | 4–6 Questions | Numerical + formula application |
JEE Advanced 2021 Overall Pattern Insight
JEE Advanced 2021 was dominated by Calculus (Maths), Mechanics (Physics), and Organic Chemistry (Chemistry). Most questions were multi-step and concept-integrated, requiring more than one concept to solve a single problem. Direct formula-based questions were limited, and many problems required application of standard concepts in modified situations rather than direct theory recall.
JEE ADVANCED FAQs
Ques: Does a candidate need to clear individual subject-wise minimum cut-offs to qualify?
Ans: Yes. To clear JEE Advanced, a candidate must clear both the minimum aggregate score requirement and the minimum marks baseline set for each individual subject (Physics, Chemistry, and Math).
Ques: How does a candidate simulate a realistic archive test at home?
Ans: By downloading past papers and solving them in two distinct blocks (9:00 AM to 12:00 PM and 2:30 PM to 5:30 PM) on a desk without looking at any answer keys or solutions during the breaks
Ques: What notable pattern shift occurred when JEE Advanced transitioned to a completely Computer-Based Test (CBT)?
Ans: The CBT shift eliminated manual OMR bubbling errors but introduced new design variations, like typing out precise decimal values for numerical questions using an on-screen mouse
