Durgendra you have mentioned all your statistics in a very confusing manner. First of all mention your overall CAT percentile properly then mention your 10th and 12th percentage properly. It is very confusing don't write informal language mention your records properly.

Assuming what you have written your academic records seems to be pretty good but its hard to judge your overall percentile and without that, I can't tell you your chance of selection in FMS.

Anyway FMS has also completely changed its grading system. Now it gives 60% weightage to CAT marks, 5% extempore, 15% Interview, 10% GD, 5% 10th class and 5% 12th class. So any way you will need to fight for those 30% marks which will make a huge difference in selections.

Comment your records below properly so that I can tell you your status.
