A comprehensive performance evaluation has brought to light the toughest question hurdles encountered by aspirants in the JEE Advanced 2026 examination. The organizing responsibility for this year's premier engineering admission test was entrusted to IIT Roorkee. Following the evaluation of candidate responses, the Joint Implementation Committee published its official performance report, presenting a question-by-question breakdown that outlines exactly where even the sharpest minds struggled to secure marks under rigorous exam conditions.
Exam Structure and Subject Difficulty Distribution
The JEE Advanced architecture is organized into two distinct sessions, namely Paper 1 and Paper 2. Both papers systematically assess candidates across Mathematics, Physics, and Chemistry. In Paper 1, candidates were required to tackle 16 questions per subject, creating an overall section volume of 48 problems. Paper 2 scaled up the question count to 18 problems per subject, generating a final collection of 54 questions for the afternoon sitting.
A total of 1.79 lakh students sat for the examination during this testing cycle, navigating an intensely demanding assessment environment. In terms of subject behavior, Mathematics turned out to be relatively approachable compared to trends witnessed in previous years. However, this relief was heavily countered by Physics and Chemistry, which posed severe conceptual hurdles and rigorously examined problem-solving accuracy.
Physics Paper 1 Question Two Emerges as the Biggest Hurdle
Data released by IIT Roorkee confirmed that question number 2 within Physics Paper 1 stood out as the single most difficult problem of the entire examination. Out of the 1.79 lakh candidates who appeared for the test, 1.28 lakh students, representing 71.89 percent of the total cohort, decided against attempting the problem altogether and left it unattempted on their answer sheets.
Even among the candidates who attempted to work through the complex derivation, success remained remarkably elusive. A total of 24,933 students, or 13.88 percent, submitted incorrect solutions. Consequently, when accounting for unanswered questions and incorrect attempts, approximately 85 percent of all examinees scored zero on this solitary Physics problem.
Over 60 Percent Candidates Avoided Four Key Chemistry Problems
Conceptual friction was equally pronounced across Chemistry, where multiple questions triggered an exceptionally high abandonment rate. The official breakdown demonstrates that at least four separate Chemistry questions saw more than 60 percent of test-takers entirely bypass any attempt to solve them.
In Chemistry Paper 1, question number 1 was skipped by 66.59 percent of aspirants, while another 19 percent registered an incorrect response, resulting in an overall failure rate of 85 percent for that item. Question number 4 in the same paper proved even more treacherous, with 62.27 percent choosing not to attempt it and 27 percent delivering wrong answers, leaving 90 percent of examinees without marks.
The pattern persisted into Chemistry Paper 2. Its opening question saw 67.42 percent non-attempts alongside 20 percent erroneous answers. Furthermore, question number 3 in Chemistry Paper 2 remained untouched by 62.45 percent of the test cohort, with 27 percent providing incorrect conclusions, denying marks to 89 percent of applicants. For aspirants targeting the 2027 entrance cycle, these metrics illustrate the paramount importance of tactical question selection during high-stakes competitive examinations.
