B.Tech Computer Science and Engineering

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.

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

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.

Hi, Both the courses are good, they have their own advantages, it purely depends on your interested and passion.

This review by a student may help you out:
JAYPEE is one of the best engineering college in India. JAYPEE is one of the few private college which better than nits and some of IITS college. Most important thing about JAYPEE is placement is very good. JAYPEE is heaven for students who want to study CS
