Now coming on to CAT percentile, competition for MBA has tremendously increased over the years and lakhs of students across India are taking up CAT exam every year which makes it a tough competition and hence a higher percentile required to fetch a good university for yourselves. 99.9 percentile is the highest that hoes across India and as per personal observation the marginal percentile equivalent to 75-80 makes it really hard for you to look for a govt. institution or a good one, you need to settle down with a marginal private institution with a percentile equal to or lesser than 80.
