PAST PAPERS BY CHAPTER
Over 11,000 JEE Main previous year questions, sorted into Physics, Chemistry and Maths chapters and topics. Filter by year, by topic, or by the questions you have not tried or got wrong. Bookmark the ones you want to come back to.

SOLUTIONS YOU CAN FOLLOW
Each solution is written out step by step: the key idea, the working, and where students usually slip. Where a question has no solution yet, the app says so.

FULL PAPERS AND MOCKS
Sit a full past JEE Main paper, or a full mock timed like the exam: 75 questions, 3 hours, +4 and −1 marking. See your score by subject and review every answer after.

DAILY ARENA
A short ranked test from Monday to Saturday: the same 10 questions for everyone that day. Your rank comes right after you submit.

DOUBT HELP
Ask about the exact question you are on. Answers are written by AI in clear steps, now with diagrams and practice questions inside the answer. Check each step, and tap Report on anything that looks wrong.

REVISION NOTES, FORMULA SHEETS AND PDFs
Each chapter has revision notes and a formula sheet; saved sheets open without the internet. Download chapter PDFs of past questions to practise on paper.

A PLAN THAT FITS YOUR HOURS
Tell the app your exam date and how many hours you have; it lays out what to study each day.

ONE ACCOUNT ON PHONE AND WEB
