These aren't very good marks for JEE Mains until and unless you are from SC/ST or OBC you wouldn't be able to clear the cut off of main and even if you belong to these categories the chances are still very low but I suggest you to go for councelling you might get the seat in end rounds of councelling but it depends upon your luck only so side by side you should also prepare a backup plan , do not just depend upon Jee Mains.

Good Luck!!.
