IIM

Hi There, There is absolutely no comparison between CAT and MAT
1. CAT is far more better than MAT as it is conducted by IIM and it is the only exam that if you crack, can give you a ticket to IIM while MAT is the least rated amongst all the entrance exams and is accepted by only low and average ranked colleges which would hardly give you any placement
2. CAT is conducted once in an year while MAT is conducted 4 times an year
If you are to take my advice, I would suggest you start preparing for CAT. Also do take up XAT and CMAT. XAT is accepted by Xaviers
3. CAT is accepted by all the colleges while MAT is only accepted by TIER 3 colleges.
