Frequently Asked Questions
Find answers to common questions.
Was JEE Main 2026 Jan 21 Shift 1 paper tough?
The paper was Moderate overall. Mathematics was relatively tougher due to lengthy multi-step calculations, but Physics and Chemistry were balanced. Students who managed their time well and had a strong NCERT foundation found the paper fair and completable within the given 3 hours.
Which section was the easiest in Jan 21 Shift 1?
Chemistry was the easiest and most scoring section in this shift. Inorganic Chemistry questions were closely based on NCERT text, Organic Chemistry had standard reactions, and Physical Chemistry numericals had clean, manageable numbers. Students strong in Chemistry had a clear scoring advantage.
Which subject was toughest in JEE Main 2026 Jan 21 Shift 1?
Mathematics was the toughest section. Questions required multi-step problem solving with lengthy calculations, particularly in Definite Integration and Vector & 3D Geometry. Students who attempted Maths without a time strategy struggled to complete the section, which hurt their overall scores.
Was the Jan 21 Shift 1 paper based on NCERT?
Yes, significantly so — especially in Chemistry and Physics theory. NCERT formed the backbone of Inorganic Chemistry questions and several Physics conceptual problems. Students who had read NCERT carefully, particularly Class 11 and 12 Chemistry, reported that many questions felt familiar and direct.
Can JEE Main 2026 Jan 21 Shift 1 be considered a high-scoring paper?
Yes, for students strong in Chemistry and Physics it was a good scoring opportunity. Chemistry alone could fetch 60–70+ marks with thorough NCERT preparation. A combined strong performance in Physics and Chemistry could cover for a moderate Mathematics score and still push overall percentile above 95.
