Hi Debasis,
Both the courses are the same, but they have different names. If you look into the course curriculum, you'll realize that it is 85-90% same. So, why you want to get into the job market a year later and pay fees for an additional year.

Loyola, SRM University and Satyabhama University are some of the well-known institutes.

It depends on your interest and your ability. If you have an interest in the science stream then go for PG i.e. M.Sc. There is a lot of scope for M.Sc graduates.

You are not eligible to take the lateral admission in B.Sc second year in Delhi University as there is no such provision in the university.
