Pune

The cut-off would be something within 50 percent of the total marks you appear for, in the exam. It might even go down to something around 45 per cent, at max.
Do not worry about that, just do well and concentrate on the paper during the exam rather than worrying about the cut-off.

1. Department of Management Sciences, University of Pune, Pune
2. MAEER's MIT School of Business, Pune
3. Vishwakarma Institute of Management, Pune

My suggestion from top to bottom order for above colleges:
1. PUMBA
2. Alkesh Dinesh Mody Institute
3. Indira
4. MITSOM

I won't recommend Durgadevi Saraf,
Indira has higher fee, though the placement is average ROI is very low for Indira.
Try for Met MMS, Alkesh Dinesh Mody Institute, SIES, Lala, etc.

Basically, if you choose to prefer location wise then in Pune, Indira is the mostly referred college after PUMBA because of its placement and all over environment.

Sorry to say but your rank is too high for computer science and IT cut-off.
If your rank had been under 800, then there were chances of getting CSE and under 1200, you might get IT but at this rank it is very difficult to grab these two branches.
I hope you understand my point.

Please check with Symbiosis Skills and Open University as this is newly started so he has better chance to get admission there. Apart from this, he can do it from Pune University externally and also search for low profile or newly started colleges where chances are high.

It's not that good.
