how can we week chapter effectively while revision for jee mains ??. as we know that revision is very important for jee mains

Hello,

While preparing for JEE Mains, make sure that you study everyday some portion of the chapters that you find tough. While doing so make sure you keep note of important points and equations in a separate book . This will come in handy at the time of revision. Now once your preparation is over start revising with the help of the notes you prepared. If you find any topic tough while revising, read through it again. Also practice previous year questiion papers and mock tests, so that you will get an idea how questions will be asked from those topics, and if you are unable to answer them then you will know you will have to read through those topics again.

Following these I am sure you will be able to do well.

Good Luck
