Hello Aman ,

Its good to know that you wanto prepare on your own for JEE.

Thing you should make sure you have is-

• Good Study material
• Good questions to practice.

Well you must know it is not easy easy to do it on your own. I will suggest you to go for UNACADEMY. Yes they will provide you with video lessons that are easy to understand and helps a lot.

You can get study material through DLP or one more site you can refer is https://www.embibe.com/landing . here you can find free resourses and good practice tests.  I have find their questions similar to that in may packages og coaching institutes.

All the best . Hope it helps.
