SASTRA (Deemed to be University) Cut-off

According to last year's stat the closing rank will be 1800 in stream 1 and 600 in stream 2
So there is chance to get a seat
Do not worry you can get a seat in nri quota but the fees will be around 5 to 6 Lacs.

If your JEE rank stands in range of 25,000-30,000. You can get CSE with your score. Try upto last round of counselling. Wish you luck.

It's difficult to get CSE with your score. Your JEE percentile is less under stream 1. You can try for other branches. Wish you luck.

It depends upon couselling, also it is difficult for you.

May be you can expect M.Tech. But don't be sure about that. Wait upto last counselling.

No exact answer can be given as admission in SASTRA is on the combined basis of boards and Mains score.
Since you have a low boards percentage, you can only get into it if you have good Mains marks.
However, the branch is non-core, hence the competition will not be much.

Yes, admission for sastra is 70% through JEE Mains + boards and rest 30% is from board merit. Moreover, for the 70% admissions, 75% are your JEE Mains marks weightage and 25% are your board marks weightage. Hence you are likely to get admissions with your better performance in Boards. Best of luck.

Eligibility: The candidate must pass +2 with an aggregate of 60% marks in Maths, Physics and Chemistry/BT/CS/Biology obtained in a single sitting.

Allotment of seat depends on availability of seat at the time of counselling.
