Hi aspirant,

Mat examination is conducted by All India Management Association (AIMA) in offer admission in various Management courses. See it is not possible to tell your percentage just from your marks as it depends upon several factors which include the number of people who appeared for examination, the difficulty level of questions and the moderation policy applied. Further more, percentile denotes percentage of people who have scored lower marks than you, so it's not just about your performance.

Hope it helps!
