Your caste plays the major roll in this .

If you belong to OC , you are not going to get seat in top 10 colleges … not even top 20 colleges unless you have a good jee mains score . There is B category in these top colleges where they take students based on jee marks . But make sure you apply it early.

If you belong to BC, you can get in top 15 colleges.

If you belong to SC/ST you can get in top 5 colleges .

In India reservation plays the major role .

Hope it is helpful.

All the best.
