Apart from CSE, mechanical, electrical, EEE and etc. You will get all branches in this college. You won't get civil but under the SSC course, you can get civil if luck favors. Hope:-
If you study well for a year keeping in your mind to enjoy rest 3 years, study hard and be consistent in first year, and keep a good CGPA and change your branch.

There are very less chances of getting this college at this rank but you can try your best for that.
