CBSE 12th

Hi, you are fully eligible for IIT JAM entrance exam. While the eligibility to apply for the entrance exam is based on the marks of graduation as it should be more than 55%.

The first thing you have to keep in mind is time management. You have to work smartly with complete dedication. In CLAT, the most scoring subject is GK, legal and then reasoning, you should first focus on these.

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

You can get a lot of colleges but the most important is to go for a government institute having a good reputation and some are SVNIRTAR, NILD, NIEPMD and PDUIPH. For admission in these, you need to qualify an All India level entrance known as CET. Check this article for more information:

Yes, absolutely you can get admission in BITS through class 12th marks. There are a lot of students studying at BITS from AP. They even have an association called Andhra Association here. See you soon at BITS.

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