HELLO,

If you want to take admissions without any entrance test for B.tech course you can consider private universities or colleges that give admissions on bases of 12th class marks

You can also explore state level counselling or direct admission program if your states offers that.

If you wanna go to government colleges try considering CUET ( COMMON UNIVERSITY ENTRANCE EXAM) .Some private universities also accepts cuet now for admissions so it will be better if you can take it .

Some private institutions highly recommended for B.Tech

1. Vit Vellore

2. Amity University , Noida

3.BTS Pilani

4.SRM university , Chennai

5.UPES Dehradun
