Sri Venkateswara College, University of Delhi

Depends on the course you want to choose. SVC is good for both arts and Science. Personally, I would recommend SVC.

Sri Venkateswara College is better when it comes to crowd and studies. Both are good but SVC is any day better.

No, admissions have been closed.

Both the colleges have equally good placement opportunities. SVC has a very dedicated placement cell. Package records have been very good in the year 2017-18 with the highest being 16 LPA.

Admission started in July and classes have already begun.
Next admission session will begin in July 2019 and the forms will be available from June 2019.

No, admissions are based on cut-off list released during may and no direct admission is possible.

Entrance Exams are conducted for this college. Have you applied for it? The admissions are currently happening. Visit college to get correct information.

Phase two counseling for Which course and college? As per my knowledge no course in DU is based upon counseling. Just a cut-off list is released as per your marks in class 12.

Seats are available but your percentage does not meet the desired cut-off (sixth list) which is 82% for OBC. Try in other colleges. If vacant seats are available and the cut-off goes down then you may check again.
