Hello Shobhit,
Yes, admission majorly take place through JEE Main score.

Hello,If you got 58 percent marks in class 12th, then you can take admission in University of Delhi.

With that percentile you cannot get admission in NITs or IITs. And even for getting admission in IITs you need to appear for JEE Advanced which will be conducted for the top INR. 2.24 lakh students who appeared for JEE Mains.

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.

Yes, it is valid for government examinations/ jobs. All the best.
