JEE Advanced 2026: These questions saw the highest wrong-answer rates among students
The JEE Advanced 2026 official report reveals which questions saw the highest wrong-response rates across Mathematics, Physics and Chemistry. Physics Paper 2, Question 14, recorded a 74.84% wrong-response rate, while several Mathematics and Chemistry questions also saw errors from more than 60% of candidates.

- Physics Paper 2, Question 14, saw 74.84% wrong responses, the highest rate in the report
- Mathematics Paper 2 had four questions where more than 64% of candidates gave wrong responses
- In Mathematics Paper 2, 56.96% skipped Question 5 and 56.35% did not attempt Question 7
The toughest part of JEE Advanced 2026 may not have been the questions candidates left unanswered. In several questions, a majority of students who appeared gave the wrong response, according to the exam's official Joint Implementation Committee (JIC) report.
The report's question-wise statistics break down how candidates performed across Mathematics, Physics and Chemistry in both papers. They record the number of candidates who did not attempt a question, secured full or partial marks, or submitted a wrong response.
The figures offer a closer look at where candidates struggled, beyond the overall marks and ranks.
Here are the JEE Advanced 2026 questions with the highest wrong-response rates:
| Subject | Paper | Question number | Candidates who gave a wrong response |
|---|---|---|---|
| Physics | Paper 2 | 14 | 74.84% |
| Physics | Paper 1 | 9 | 69.01% |
| Physics | Paper 2 | 13 | 67.79% |
| Chemistry | Paper 1 | 10 | 67.06% |
| Mathematics | Paper 2 | 11 | 67.24% |
| Chemistry | Paper 2 | 13 | 66.51% |
| Mathematics | Paper 2 | 14 | 66.49% |
| Mathematics | Paper 2 | 18 | 66.01% |
| Mathematics | Paper 2 | 13 | 64.76% |
| Chemistry | Paper 2 | 15 | 64.53% |
| Physics | Paper 1 | 12 | 66.64% |
PHYSICS HAD THE HIGHEST WRONG-ANSWER RATE
Physics Paper 2, Question 14, recorded the highest wrong-response rate among the questions listed in the report. A total of 74.84% of candidates gave the wrong response. Only 10.59% did not attempt it.
Physics Paper 2, Question 13, also saw a high wrong-response rate of 67.79%. In Physics Paper 1, Question 9, 69.01% of candidates gave a wrong response, while 66.64% did so for Question 12.
MATHEMATICS PAPER 2 STUMPED CANDIDATES
Mathematics Paper 2 had several questions where wrong responses crossed the 60% mark. Question 11 recorded a wrong-response rate of 67.24%, followed by Question 14 at 66.49%, Question 18 at 66.01% and Question 13 at 64.76%.
The numbers also show a different challenge: questions candidates chose not to attempt. In Mathematics Paper 2, 56.96% skipped Question 5, while 56.35% did not attempt Question 7. These figures do not establish why students left the questions unanswered, but they show where the paper saw substantial non-attempt rates.
CHEMISTRY ALSO HAD QUESTIONS WITH HIGH ERROR RATES
In Chemistry Paper 2, Question 13 recorded a wrong-response rate of 66.51%, while Question 15 saw 64.53%. Chemistry Paper 1, Question 10, had a 67.06% wrong-response rate.
These percentages are not, by themselves, a complete measure of question difficulty. They show how candidates responded, rather than explaining whether a question was conceptually difficult, time-consuming or prone to mistakes.
For students preparing for future attempts, the data offers a useful starting point: revisit questions with high error rates, examine the concepts and methods involved, and distinguish gaps in understanding from errors made under exam pressure.
