B.Tech Computer Science and Engineering

Hello Shreyash,
B.Tech in CSE and B.Tech in software engineering are almost similar with minor variations. While B.Tech in software engineering focuses only on software, B.Tech in CSE maintain a balance between software and hardware. Unless and until you get a job in a hardware company like Intel, Logitech etc., this difference hardly matters. Most of the IT jobs are available in the software domain. So, don't judge or get confused between these two branches. Just choose one in a good college.

If you want to do a job related to CSE, then you can pursue some certification course. Otherwise, if you want to pursue higher education, then you can go for GMAT or CAT exam.
All the best.

Yes, you can say that the course is similar but degree is different.

You need to clear GRE/GMAT/TOFEL to get into MS course from foreign university. Doing MBA from a premiere B-School in India is of similar cost as that of doing MS from abroad. As you have completed B.Tech in CSE you can go for computers related subjects like AI and analytics.

The eligibility criteria for selection in TU is 60% in your PCM at 12 level and 20% weightage of your JEE score. According to your score, I feel there are chances for your selection.
Good luck and best wishes.

NIT-Silchar, NIT-Agartala, IIT-Guwahati are known institutes for B.Tech in CSE. Other good colleges you can find in Kolkata like Heritage, Techno India, etc.

NSIT Delhi offers both BE Computer Engineering and BE Information Technology degree courses.

You can go for any of the branch. Both the branches have a wide scope and opportunities available. CS has a little more opportunities than IT, but in terms of career and growth both are equivalent.

You will have to approach the college administration.
Its easy to get a lateral entry.
