You won't get admission in NIT's or IIT's. You can get admission in general private institutes, just know the nearby private institutes near you locality.

Well, you should decide it by your own. If you are confident that you will clear the JEE next year, then only you should drop. Otherwise, don't waste your time and get admission in engineering college. There are so many private college, which are also providing best education and placements as well. So, no need to be worry about getting IITs or NITs. All the best.

Depends on your rank in JEE Mains. Check this link for cut-offs in NIT-K (Surathkal):

If you want to drop, then you have to make a strong decision and work to prepare for both RBSE 12th exam and JEE Mains. If you are dropping, then make it useful rather than wasting your time.

Hi Deepanshu,
The marks of class 12th are not important for admission in YMCA, only the rank in JEE Mains is important.
My best wishes.
All the very best.

IIIT-Ranchi is newly constructed college. As far as NIT-Agartala is concerned, it is one of the oldest NITs. The other factor you can consider, is if you haven't got branch of your choice, then you can go for Ranchi instead of studying halfheartedly for Civil, but overall NITA is much better option.

No, first you are not qualifying the criteria for 10 + 2 percentile, and second you have to give JEE Mains for sure.
