Hello Aspirant.

To get admission into DTU you need to clear JEE main examination at a desired rank. But to be eligible to get college through JEE main examination you need to score atleast 65%(For sc/st) in class 12th. And 75%(general).

Hence, in your case as you've not scored minimum eligibility criteria marks, you're not eligible to get any college through JEE main examination.

Best of luck
