I got 2040 daiict marit rank and 30303 all india rank general category.

can i get admission in daiict or nits??

if not then suggest some good colleges fits in this rank criteria. I M from Gujarat state.

For this rank as from previous year records it is not feasible for you to get IICT Gandhinagar and AIR rank is not considered your state rank will matter in the final admissions. You can look in for some good private colleges who give admissions on the basis of AIR ranks.
