Kakatiya University

Sorry, but you can't give B.Com because you need to clear 10+2 exams but since you have only completed 10th, you have to study for more two years from commerce stream and then, you can apply for you graduation degree from commerce background.

Well, if you have appeared for JEE Mains and got a good score, you can drop out and can apply for NITs. Instead of going to some last ranked NIT, I prefer you to stick with the current Institute you are studying at present and complete the B.Tech. Later if you wish you can prepare for higher studies and get admission in NITs or IITs for your PG.
