B.Sc

If your current college is affiliated to MGU, only then it is possible to do so. But then again, you will have to check if there are seats vacant in MGU and state a proper and solid reason for the change.

B.Sc. in Agriculture has better recruitments in government departments. Fishery is also good but it is not better than Agriculture. The demand of Agriculture is in nearly every department like Banks, Public welfare, Forest departments etc.
