MAT

This score is good but you won't get a good college through this score.

CAT is known for its toughness. There might be some little changes in the syllabus. If you want to write other exams after preparing for CAT you can do that. But you have to prepare some extra topics apart from your CAT syllabus to write your prescribed exam.

The college does not gives admission to students who have below 50% in graduation

Hi,
Yes, they accept MAT score for MBA admission. Please find the link below:

As your score is much lower in MAT, but it depends upon the college whether they will provide you admission or not, you can apply after that it will be depending on them whether they will give you admission or not. All the best.

Hi,
Compared to other exams, MAT is same, but in MAT you get chances if you fail to clear once you have another chance to attend it compared to other exams. Yes, MAT is also tough but not that tough as CAT.

It's difficult to get admission in a B-School with this score, they are much lower, you need to score more for getting a good college.
All the best.

First of all, congratulations on your score. Any MAT score above 90 percentile can get you admissions in the top MBA colleges. I am sure that you would have known the top colleges by now. So, choose the college wisely considering the specializations you are interested to take. All the best.
