Hello Purushottam

It will depend upon the specific college and branch.

And admission is based on the rank only.

So you have to secure rank under 5-6 thousand for the cs in good college.

And around 8-10 thousand for e&e.

For mettalergicul it more than 10 thousand

(Vary according the the state and your category and some other conditions).

And to secure rank under 10-15 thousand you have to score 99 + percentile marks.So that you have good options with you.

Good luck.
