Department of Management Studies IIT Delhi Hauz khas Answered Questions

To be frank your SI score will be very low with these marks. IIT, Delhi takes into consideration all the marks and extra-curricular. Students even with good CAT score don't make it to next stage if SI score is low. So as per my understanding, it is very difficult to get in even 1st stage of the process with these marks if you are a general category student.

The list for the batch of 2018-20 is already out. If you have applied please check here:
