Admission to DTU is only based 12th marks as well as JEE Main marks. So you just need to score very good and enough marks for getting admission in college. But according to DTU eligibility criteria, the minimum percentage is 75 in 12 for being eligible for admission. It doesn't mean that you are now selected. You are just eligible for the admission. Now if you score very good marks in JEE Main then you may easily get the admission. I will advice you to score more in 12 like 85+ since the cut off is very high and in JEE Main you must score near 200 if you are under general category. Best of luck. For any further query please feel free to ask.
