Manipal Institute of Technology

Yes, you will get ECE in Manipal University with your rank.

BITS Pilani is a better option over MIT Manipal.

It is difficult to get Aeronautical with that score since the cutoff has been going higher every year. You should definitely try for multiple rounds of counseling and giving your name for the waitlist. Considering the increased intake of the branch, you might be able to manage a seat.

First of all congratulations for your results!!
If you get that there is no issue of branch. You should take as per your field of interest. You are more likely to get all good branches like CSE,ECE and aeronautical as well. You can try for that.
Hope this helps you.

Sorry, your marks are not so good to get into Manipal University but you have to try for any other college except that which is better than this college.

No, you will not be able to get CSE with that score in the exam.

Manipal has increased the intake in Automobile Engineering. So, you may get Automobile Engineering in counseling.

There is a possibility of you getting CSE in the first round of counseling itself. If not, you should give your name for wait-list. You'll get it in the later rounds of counseling for sure.
