Some of my friends studied at Pondicherry University. According to them, they offer three Integrated M.Sc programs –

• Mathematics, Statistics and Computer Science
• Physics, Chemistry and Applied Geology
• History, Sociology and Political Science

You will have to choose from these three disciplines only and then choose the major subject among them. 

The advantages of the course and university are listed below.

• You can exit the course after three years with a B.Sc degree.
• The syllabus is light even though there are three major subjects and thus you can take up any additional courses you like.
• The university offers freedom in terms of uniform, timetable, and everything else while many of the undergraduate colleges still have school-like rules.
• You can study an undergraduate course from a university which is pretty rare.

Studying 5 years in an Arts stream is difficult and should be reconsidered. The best course is Physics, Chemistry, and Applied Geology. Doing M.Sc in Computer Science is also not a good idea.
