JEE Advanced

Admissions in LNMIIT is on the basis of JEE Mains score and not rank. The basic cut-off is that you should have cleared Mains. Individual branches cut-offs are announced later based on the number of seats available for the course.

If you have a good percentage in 12th as well, by good I mean like 90+; then there are chances that you can get into a NIT. Moreover, CSE is a highly prioritized branch, for that you can go for your home state NIT. And the chances increase if you get category reservation.
Good luck with that!

You score should be a minimum of 200 this year.

Obviously, you will get as your rank will be around 1000-1500. If you belong to OBC/SC/ST then you will get CSE in the top 5 IITs. In case of general category, you will get CSE in IIT Roorkee or IIT BHU or IIT Guwahati. But from this year, this trend may change. Best of luck!

Hello Vinay,
The BITSAT scores are not considered for admission into IITs. Only the JEE Advanced scores and your ranks determine your admission into IITs. I think you can get IITs, but if you don't, then go for BITS as you are saying that you are having a good score in BITSAT.
Both are almost equal but BITs Pilani is a private university, whereas IIT is a government one so fee structure will be a huge difference.

You need to qualify JEE Mains and then Advanced. On the result day of Advanced and I guess till one or two day later you can fill AAT. Upon qualifying AAT, you will be allotted college in B.Arch of IIT KGP & Roorkee on the basis of JEE Advanced rank.

It is almost impossible to get a seat in IIT Delhi in any branch after a rank of 10000. However, it may be possible in IIT Kharagpur if you have filled up for Architecture. Otherwise, it looks difficult.
