Chemistry recently shifted away from basic memory-based questions and towards integrated multi-concept issues, whilst Physics featured more statement-based questions.
3. What is the expected 99 percentile score for this shift?
Due to the unexpected difficulty of the Chemistry part and the calculative nature of Mathematics, the cut-off for a 99th percentile is expected to be lower than normal, perhaps falling between 170 and 180 marks.
4. How many questions are there in JEE Mains Paper 1?
As per the JEE Main paper pattern, there are a total of 75 questions totaling 300 marks asked from physics, chemistry, and mathematics.
5. Why is a JEE Main Mock Test necessary for my April session preparation?
JEE Main Mock Test is essential for improving time management and the “pick and choose” strategy. Practising with mocks teaches you how to “skip and move on” from difficult questions to identify the 30-35 “doable” ones that will help you improve your score.
6. How was JEE Mains Physics Questions in Jan 28 Shift 2 Paper?
The overall question is easy, but the paper was lengthy. Key topics of this shift were Ray optics, electrostatics, semiconductors, SHM, current electricity, rotation, moment of inertia, fluid mechanics, Potentiometer, vernier calliper, and thermodynamics.
7. What are high weightage of chapters in jee mains Chemistry section?
