Hello aspirate

Your rank is not so good to get computer science engineering branch as the cut off goes high for this branch . You didn't mentioned your category, if you belong to sc/st then you have more chances of getting nit with the desired branch.

I would suggest you to use career360 jee main college predictor to know the nits you can get with this rank
