JEE

With 52 percentile in JEE Mains, here is one college I was able to find:

International Institute of Management, Engineering & Technology:
Fee: INR 2.02 Lakhs, which is equal to 25,000 per semester (6 months)
Eligibility: Candidate must have passed 10+2 from any government-recognised board
Seats: 240

Apart from that if you belong to SC/ST/OBC/EWS you can also get some scholarship to get some help financially.

I hope it will help.
