Hi Swati, generally the cutoff stays around 70 percentile with no sectional scores. Now this percentile you obtained seems to be close one. My opinion is just dont be expecting only a single college try for various other options available with the obtained percentile. If you feel you want to be part of that single college try it around next year if you are so much determined. The situation here is 50-50 to be straight. 

All the Institutes are decent. My preference would be IMT Hyd > IFIM Bangalore > IMT Nagpur based on overall learning experience, campus life, city connectivity, corporate connect & location. IMT Dubai will not be in my list as I am not sure what extra ROI I may get from Dubai compared to the expenses. 

Fees at IFIM Bangalore 9.5 Lacs (w.o hostel); IMT Hyderabad & IMT Nagpur 12 Lacs (include hostel fee) are almost the same. 

Avg. Placement figures - IFIM Bangalore 7.12 lpa, IMT Nagpur 7.5 lpa & IMT Hyderabad 7 lpa, for the batch 2016-18, more than 85% student placed. More all 3 are in similar category but as I said, out of the 3, I shall pick IMT Hyderabad for the campus, learning, faculty bonding, Corporate connect etc.
