B.Tech Computer Science and Engineering

You should go for Thapar if you are not getting a good college like IIIT.

Hello,
There are many colleges in Delhi for B.Tech in CSE branch. Refer the following link:

According to my knowledge, you will get admission on the basis of JEE Mains score. There is no good university provide admission on the basis of class 12th. Good luck.

Please use college comparison tool:

You can pursue B.Tech in Computer Science and Engineering (CSE) Four Years Duration Course from SRM University, Sonepat, Haryana, and Delhi-NCR.

Good luck.

All three are good placement wise but cloud computing is most trending in market. There is a lot of demand but students of CSE also got good placement opportunities this year.
Cloud is having some advance subject syllabus so you can go with cloud computing.
All the best.

According to my knowledge, SRM University is best option for B.Tech CSE. You should take admission here. Good luck.

As your percentile are low, so there is less possibility that you get a good engineering college. So, you can apply any private college or if you want a good college, then you should again prepare for JEE.
Good luck.
