Frequently Asked Questions
Find answers to common questions.
What was the overall difficulty level of JEE Main 2026 January 28 Shift 1?
The overall difficulty level was moderate. Physics was concept-based and manageable, Chemistry was NCERT-driven and scoring, and Mathematics was the most challenging section due to lengthy, multi-step calculations. Students with strong fundamentals and good time management were able to attempt 45–50 questions accurately.
Which section was the toughest in Jan 28 Shift 1?
Mathematics was the toughest section. It involved multi-step calculations and lengthy questions — particularly in Calculus, Vector & 3D Geometry, and Conic Sections. Students reported running short on time even when they knew the method to solve the questions.
Was Chemistry NCERT-based in this shift?
Yes, Chemistry questions were predominantly based on NCERT Class 11 and Class 12 content. Topics like Coordination Compounds, Biomolecules, and Organic Reaction Mechanisms were directly NCERT-aligned. Students who had read NCERT text thoroughly found this section the most straightforward of all three.
How many attempts are considered good in this shift for 99 percentile?
Attempting 45–50 questions with high accuracy is considered the benchmark for 99+ percentile in this shift. Accuracy matters more than attempt count in JEE Main because of the –1 negative marking on incorrect MCQ answers. Attempting fewer questions correctly is better than attempting more with errors.
What score is needed for 97–98 percentile in Jan 28 Shift 1?
Based on the observed difficulty level of this shift, a score of approximately 150–170 marks is expected to yield 97–98 percentile. These are indicative estimates; actual percentile figures depend on NTA's normalisation process across all shifts and sessions.
