Hello Aspirant

For the fast revision the best way is to attempt tge regular mock tests and go through the best reference books and also you must be fit mentally and physically.

And the other thing is you can watch the youtube video lectures by experts that make u strong enough and helps u gaining more knowledge....and the knowledge you get more from listening from experts than reading

And u should write mock tests and they are available in careers360 portal
