Which is better for BS + MS integrated cource,if we see academic prospects ,NISER or ISERC - Vishwabharti.

The academic programmes at NISER are deemed to be conducted through the Institute of Physics, Bhubaneswar, which is affiliated to Homi Bhabha National Institute. NISER insists on student evaluation of each course and the concerned instructor at the end of each semester. This is an important part of a self-correcting process. Students are encouraged to think in terms of making a qualitative difference in their learning outcomes rather than merely attend classes.
