Hi Yogita

Yes, you can pursue an MSc in chemistry 2-year program as a private student after completing a 4-year regular course. But this depends on the college policies. If colleges' policies accept the admission of those students who completed a 4-year regular course and want to pursue the MSc program as private students.

But if college policies don't allow students to retake admission who do a 4-year regular course and want to do MSc as a private student. So, the best way you need to contact to the college administration of Guna College. Otherwise, give the PG entrance exam and try to take admission in another college.

I hope this information helps you.

Thank You.
