Hello Aspirant ,

No , PCB (Physics , Chemistry , Biology ) students can not take admission in Delhi University for BSc Physics Honors only PCM students are allowed for admission as you have to calculate your aggregate percentage and merit  with Physics , Chemistry and Maths .

You need  minimum 55%  marks in the aggregate of Physics, Chemistry & Biology and 50%  marks in one compulsory language .

Yes , some colleges do not give remarks clearly is the colleges faults.

Hope this helps.
