How can I get materials for preparation of CAT by some reputed institutions like TIME, Career Launcher, etc.?

Hello,
Well you can do certain things upon which you can get a material of top coaching institute.
Firstly what you can do is to enroll yourself online or download their app. They give some material as sample to online user. Go and check their websites and look out for resources section/ download section. Secondly you can borrow study material from your friends who are going there for coaching
Lastly what you can do is go-to YouTube and search there. You will find good informative videos and you won't be looking here and there for materials.
I wish you all the best.
Cheers !!
