CAT

Graduation with 50% or above can easily apply for CAT exam. All the best.

If not CAT, then go for ATMA XAT MH-CET, CMAT TISS (if you are an engineering).

It all depends on your preparation. If you are well prepared, practiced a lot, then you will be able to crack CAT (not easily, but yes you can, by putting a little bit of effort).

For graduation courses, candidates who have appeared for 10+2 exam are also eligible. The qualifying marks for SEBC candidates from the state of Kerala is 55% in aggregate and minimum 50% marks in mathematics as well. An overall 50% marks in aggregate is required apply for CUSAT CAT.

Yes, you will get a call from IIM but not from the top ones, since they need 99 percentile.

Any score of 99.6+ is good with that profile for IIM, Ahmedabad.
All the best. I hope you get that score.
