JEE Main Scores

Yes, if you are from SC category then chances are maximum. What is your percentage in 12th?

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!

In case you have category quota, you might hold a chance to get into the home state probably. Yes, chances are quite less. But you might be lucky enough to get it.
So, good luck!

For which state are you looking for?
And mention the branch which you are looking for?

Yes, you can easily get a seat with this rank in NIT.

Sorry but unless you are from some reserved class, you won't get into any of the NITs or IIITs.

You can apply but not on the basis of JEE Mains score. A score of 20 is not acceptable. Minimum acceptable score for ST category students is 27. Apply to the colleges which are having their own entrance exams.

Sorry to say but with these marks, you can't get any govt. college until and unless you belong to SC/ST category but the chances are slim for them as well.
Best of luck!
