Hi aspirant,

Firstly you should go through all the information available about the CAT exam.

The minimum eligibility required for the exam is : Candidates must have a bachelor's degree in any discipline with minimum of 50% ( 45% marks for SC/ST/PwD Candidates) marks from any of the recognised universities in India.

You can prepare for the exam on your own and you can opt for coaching classes also. All you need to do is be regular with your studies and attempt Mock tests on a daily basis. Smart work is the most important aspect for CAT preparation.

I can help you with some good coaching institutes and some tips for the exam  also if you let me know about your city.
