Engineering Entrance Exam

You might get NIT - Srinagar, Patna but you should focus on advance.

The official answer will be soon going to upload by the CBSE. Then only you will clear your doubt regarding your query. But however you can check it on NET of different coaching institute provided their own answer key
But, I suggest you to go according to the official key only. The answer key will release in the upcoming weeks only.

DY Patil takes admission only on the basis of JEE Mains exam, not on the basis of advance.
