What this site is
Yukti Vault is a free JEE Mathematics practice site. It lets students solve past-year questions chapter by chapter and read step-by-step solutions.
Where the questions come from
- JEE Main questions are from the official question papers published by the National Testing Agency (NTA), with answers checked against NTA's published final answer keys where a key exists.
- JEE Advanced questions are from the past papers published by the IIT that organised that year's exam.
The questions are reproduced only so students can practise them. The copyright in the original question papers belongs to their owners (NTA and the JEE Advanced organising institute). Yukti Vault does not claim ownership of them and is not affiliated with, or endorsed by, NTA, the IITs or the Joint Admission Board.
Solutions
The solutions are written for Yukti Vault, with the help of AI tools, and checked against the official answer key wherever one is available. They can still contain mistakes. If an answer or step looks wrong, please tell us. For anything that matters, check against your teacher or the official answer key.
