Can I get admission into SOL DU from a Regular DU in my 2nd year?

Unfortunately no, there is no provision for transfer from SOL to a regular college at University of Delhi. It is so because SOL is an institution in itself, like any other college.

You can try to migrate into some other college but you will not be granted admission if your scores in SOL exams are not very high.

The students of SOL are often looked down upon when compared to regular colleges. Your marks will be scrutinized before you are allowed to migrate to the college. Most students are turned down because that would mean an increase in the workload.
