I am a general category non engineer fresher who scored 89.5 percentile in the CAT. Can I get a call from GIM? Also which college is better between TAPMI and FORE in terms of placements and ROI?

To get admission in GIM Goa, I think 89.5 percentile and general non-engineer is a decent profile. People start to get admissions into baby IIMs from 93-94 percentile, so it seems easy at this profile all you need to do is excel in the interview and group discussion (if GIM organizes one). 

Between TAPMI and FORE, you can go for TAPMI, as it offers good placements and a good lifestyle, FORE is also a good option if you are a Delhi or nearby resident I would suggest opting for FORE, as the ROI for both the institutes are almost identical. Still, apart from ROI, TAPMI excels in other parameters.
