Am I eligible for MBA at XIME? I have 77 percentile in September 2014 MAT.

Yes Aishwarya You are eligible because last year cutoff was 65 percentile in any one of CAT/MAT/XAT/CMAT.But there is slight probability that it may change.So my personal advice is that it would be safer if you write any one of CAT/XAT to create better chances of admission.But as per your percentile

Score is not extraordinarily well but still you can try .even you have lot of time to apply, you can again take MAT and try to score better, it'll increase your chances to convert XIME.
