JEE Main — the qualifier
Conducted by the NTA twice a year, JEE Main is a computer-based test of 90 questions (Physics, Chemistry, Mathematics) over 3 hours. Score on a normalised percentile. Marking is +4 / -1 for MCQs and +4 / 0 for numericals. Your best of two attempts counts.
JEE Advanced — the IIT gate
Two papers of 3 hours each, multi-select MCQs, numerical answer types, and matching. Far less predictable, far more punishing. Top 2.5 lakh JEE Main qualifiers compete for ~17,000 IIT seats.
Where students lose marks
- Main — silly mistakes in PCM, poor section timing, weak coordinate geometry and chemical bonding.
- Advanced — partial-marking traps in multi-select, mis-reading paragraph-type questions, panic in paper 2.
The 12-week mock plan
Weeks 1 to 6 — alternate between a JEE Main full mock and topic drills. Weeks 7 to 12 — graduate to JEE Advanced paper-style mocks twice a week.
