No year drop is not a problem in DU as you'll only need to show in certificate what you did last year so apply the coaching certificate and there is not such problem but priority is given to fresh passouts of 12 if your percentage is high this also is not a problem to you.
greetings aparna,
no. dropping an year will be no problem in delhi university.
some colleges may demand for a gap certificate so keep that in hand well in advance. some may not ask for it but its good if you submit it. it is basically an undertaking about what you did in the gap year.
keep a check on the du website for all admission related updates.
you may take admission in honours courses like physics, maths, stats, chem, CS, microbiology etc or Bsc prog courses like life sciences, physical sciences etc depending on your marks and preferences.
refer to the link below for the previous year cut-off to get an idea:

good luck
