Dear Priyansh
That's a good percentage.
There are some colleges of engineering which gives admission on 12th base:

Shreemati Nathibai Damodar Thackersey University - Mumbai, Maharashtra

Bengal Engineering And Science University - Howra, West Bengal

Jabalpur Engineering College - Jabalpur, Madhya Pradesh

Saveetha University - Chennai, Tamil Nadu

Coimbatore Institute of Technology - Coimbatore, Tamil Nadu

Merit International Institute Of Business Management - ooty, Tamil Nadu

College of Engineering - Ahmednagar, Maharashtra

Amrutvahini College Of Engineering - Ahmednagar, Maharashtra
If you'd have taken some exams like AIEEE, BITSAT, VITSAT etc.., they'll be really good when compared to the above ones.
Ping me, if you need any help.

To get enroled in good engineering colleges you will have to appear for various competitive exams like jEE Mains, BITSAT, SRM etc..Have you applied in any such entrance?
