Hi,

The admission to integrated M.Sc programs in iisc is taken through the JAM exam followed by a interview.

If you want to do only Master's at iisc you can take exit and opt M.Sc only. In that case a MS thesis must be submitted by the end of third year after giving the colloquium. It means if you leave with msc.degree only you are required to complete it in three years.

After completing the M.Sc from iisc you can do Ph.D course from other university if you want.

Hope this helps.
