2. Sydenham Institute of Management Studies, Research and Entrepreneurship Education(SIMSREE).
3. K. J. Somaiya Institute of Management Studies and Research(SIMSR).

Since you are planning to pursue MBA in HR in Mumbai. I would suggest, you should opt for some government college or reputed B-school instead of ITM.
Following are few good colleges:
1.MET
2. S.P JAIN

If you want to continue your job with MBA, then you can go for distance education. Otherwise, you should go for a full-time MBA course. You will get more exposure and more practical knowledge about corporate environment.

There is no cut-off as such. A decent percentile (around 75-80 minimum) with good past academics may give you a good chance for getting a call. Work experience and extra-curricular may give you an edge.

Both the campuses are good but you can prefer Pune campus.
