JEE Main

No IITs can be opted through JEE Mains exam. You have to first clear JEE Mains and JEE Advanced exam.

I wouldn't suggest you to drop 1 year, because you will need to study extra hard to beat JEE Mains. But, if you really want to prepare, Kotak is best option for you.

No, 70% marks score is too low to be considered for admission in any good private college. I would suggest you to study well and try again next year.

No, B.Arch in top college requires much better marks than these. I would suggest you to try hard again next year to get top colleges.

IITS are awarded to Advance top ranking students. NITs are awarded to Mains top ranking student. Getting IIT through Mains is not possible at all. And NITs are not possible at this rank too.

No, CSE at NIT JSR is not possible. You may get other branches for sure. Don't just rush for CSE. Make a wise decision and if u even get IT ECE and if it interests you, go for it. Those are good branches too. Hope it helps.

Yes, you can definitely get a seat in the mentioned college.
All the best for your bright future.

Firstly, you should have to fill the form of 2019 which come around in December. And then, you have to fill the form of JEE Mains, which came early, due to two paper in one year. On the basis of you're JEE Mains score, you can get a seat and you can also come in Kashmiri Muslim quota, so it will help you much.

You rank is quit low to get into the IET and JSS. Otherwise, your rank is good enough to get into the Galgotias, GL Bajaj, KIET and ABES.

This year, you to should target for the 160+ in the JEE Mains and 135+ in the WBJEE to get the admission in this college.
