Maths Paper 1 Question 11 had the greatest difficulty index. A number of questions in Maths, Physics, and Chemistry were rated over 85% in terms of difficulty index. In addition, Chemistry Paper 1 Question 14 had the lowest difficulty index amongst the questions that were analysed. There are questions that students made mistakes in despite having attempted them.
The difficulty index is helpful in evaluating the performance of students on a comparative basis across various questions. The difficulty index being high implies that the question was difficult for the students, and a low difficulty index implies easy performance.
In all three subjects under discussion, it is observed that there were many questions from the subject of Maths which had a very high difficulty index. These were from the topics of relations and functions, permutations and combinations, and calculus. From the subject of Physics, questions from rotational motion, fluid mechanics, and thermodynamics were difficult. It will also give students an insight into the JEE Advanced Exam pattern.

Question 14 in Chemistry Paper 1 is the least difficult of these questions, with a difficulty index of 31.4, whereby most of the students who answered this question scored full marks.
Questions 14 in Physics Paper 1 and 16 in Mathematics Paper 1 are relatively scoring questions from their full-marks percentages.
Difficulty and trickiness are somewhat different. The difficulty may be that the problem is too complex and involves many calculations or knowledge of complex theories, while trickiness will cause a mistake in solving the problem after its solution.
Trap rate statistics are useful for finding problems that led students in the wrong direction. Below are some JEE Advanced 2026 tricky questions:
Subject/Paper | Question | Trap Rate | % Not Attempted | % Full Marks | % Wrong | Difficulty Index | Chapter |
Maths Paper 1 | 9 | 99.8% | 34.2% | 0.1% | 65.7% | 86.7 | Sets, Relations and Functions |
Chemistry Paper 2 | 15 | 99.2% | 34.9% | 0.5% | 64.5% | 86.5 | Solutions |
Maths Paper 2 | 10 | 99.0% | 33.2% | 0.7% | 66.2% | 86.0 | Sets, Relations and Functions |
Maths Paper 1 | 11 | 98.8% | 38.2% | 0.7% | 61.1% | 86.9 | Permutations and combinations |
Maths Paper 2 | 14 | 98.5% | 32.5% | 1.0% | 66.5% | 85.6 | Limits, Continuity and Differentiability |
Question number 9 in Maths Paper 1 has the highest trap rate of 99.8%, while the difficulty index is equally high at 86.7%, and only 0.1% of students got full marks. This question is one of the best examples of a question that is both difficult and tricky.
Another question that deserves mention is question 15 of Chemistry Paper 2. It has a trap rate of 99.2%, while 64.5% of students got it wrong.
The question-level information reveals that both Paper 1 and Paper 2 of JEE Advanced 2026 had some hard questions, though the distribution was not the same for all subjects. The number of questions with the the highest difficulty index is slightly higher in the case of Paper 2, especially in Maths, Physics, and Chemistry. It is important for students who will be appearing for the JEE Advanced 2027 exam to ensure conceptual clarity and learn to judge between good questions and traps.
Subject | Highest Difficulty Index in Paper 1 | Highest Difficulty Index in Paper 2 | Paper |
Mathematics | 86.9 | 86.6 | Paper 1 |
Physics | 84.9 | 86.7 | Paper 2 |
Chemistry | 78.6 | 86.5 | Paper 2 |

JEE Main and JEE Advanced are both national-level engineering entrance examinations, but they serve different purposes.
JEE Main is conducted for admission to NITs, IIITs and other participating engineering institutes. It is also the qualifying examination for appearing in JEE Advanced.
JEE Advanced is conducted for admission to the IITs
Start your JEE preparation from Class 11 itself by building strong concepts in Physics, Chemistry and Mathematics. Follow your Class 11 syllabus systematically and avoid studying only for board examinations.
A good approach is:
Complete each chapter conceptually and solve basic questions first.
Gradually move to JEE-level problems.
Practise previous-year
After qualifying JEE Advanced and getting an IIT, there is no single course that is best for everyone. Your choice should depend on interest, rank, career goals and the branch available to you.
Generally:
CSE/AI/Data Science – good for software, AI, data and technology careers.
Electrical Engineering – useful for
Hello Student, I can definitely help you create a balanced plan, but I would not recommend preparing JEE , NEET , KCET , MHT-CET and school exams as five completely separate syllabi. Your Class 11 NCERT/board concepts should become the common base, with JEE-level Maths/Physics and NEET-level Biology/Chemistry added according
