It depends on your class 12 Percentage and the course which will u opt for higer education.

For physics(H), chemistry (H) and mathematics (H) etc merit list always more than 95%.for physics and chemistry your pcm osubject Marks would be calculated.

For mathematics (H) pcm + language marks would be calculated.

The another factor is that the category which do u belong.

If u belong to general category then Merit list will not be lowered than 95%

Several courses r there so select the best one in which u r interested more.

So it's better to achieve high percentage in class 12.

Fill the delhi University form and apply for all the courses and when the cutoff will release see the college Merit and opt the best course from all of them ( which u have applied) and u can get the admission easily.

FOR BSC PHYSICAL IT WILL BE AROUND 85% (LAST ROUND)

Thank you..
