Dear aspirant

At first lots of congratulations for your results . You have not mentioned that your are from which category. So I assume you as an general category candidate. According to trends of previous years and this year's JEE MAIN cut off I am afraid to inform you that your chances of getting admission into colleges NIT's and IIT's are almost negative. However You can try in state level counselling and private colleges .  But if you have any other category rank like ST , SC , OBC there may be chance for you  .One thing is very important that admission in those above mentioned category entirey depends upon that particular category rank , not the Al India rank.

you can check previous years cut off
