Hello Aspirant! With this rank, it would be quite difficult for you to get admission in DTU or IIITD with CSE branch. These are top tier colleges and take candidates with a rank below 15000. Also, if you're not from home state it's more difficult. However, you can try participating till the 5th or special rounds conducted further as there may be variations in the rank. You may get a lower branch in any of the colleges under JAC Delhi counselling but not CSE or ECE.
