Hi

90% is a decent score for getting admission in Delhi University. You want to pursue computer science hons and belong to the general category. Since, cut offs are getting really very high this year so it's difficult to estimate accurately whether you may get a seat in third cut off or not. However, with this much score, you can get a seat in closing cut offs. This estimation is based on the previous cut off trends.

You can predict the chances of getting college with the help of du college predictor here -
