Dear student,

The last year cutoff for the mathematics and computing was 18928 in the last i.e. spot round of counselling and according to your if we add 30 more seats then there might be a chance that it can jump up to 35-40K but not too much. As you got 45K rank so there is a very less chance that you can get mathematics and computing in the DTU.

Moreover you can get branches like Electrical, mechanical and all other lower branches.

You can use this link to find some other good colleges for yourself according to your rank.
