Hello Aspirant,

First of all let me make you clear that seats of B.Sc in Computer Science in Delhi University are only filled through class 12th percentage so there is nothing to do with JEE-Main rank for admission in DU. Now with this rank I would recommend you to either go for some private engineering colleges or state government colleges. You can also take a drop for this year and prepare for JEE-Main 2021 and to help you in your preparation we have some resources which you can access from the link given below :-

However I would also recommend you to use JEE-Main College Predictor to predict the chances of your admission in different colleges  based upon your percentile and category :-

I hope this information helps you.

Good Luck!!
