CAT

You need to score minimum 50% to be eligible to CAT or MAT. You can take coaching or do self-study for CAT exam.

According to me, for the preparation of CAT, you can join the endeavor classes in Ahmedabad. It is the best classes for CAT and CMAT.

Hi Shahbaaz. The total seats in PGDM in BIMM is 300+ including marketing, HR, finance, operation and system batch. The cut off doesn't have that importance here as you have to as minimum 50% is required in any entrance exams to be eligible for GD/PI. You only have to give best performance in GD/PI where you have highest score in your hand of 70% based on your performance in GD/PI.

No without writing CAT orMAT you are not eligible for that college.

Mock CATs often are clear indication of your percentile in CATs. You need to analyze where you are going wrong and correct those mistakes. Very rarely is there a deflection from the mock CATs and CAT percentile. Practice makes perfect.
Best of luck.

It is always difficult to predict the accurate percentile, irrespective of the number of questions attempted. If you don't solve any question in CAT, then you can expect anything around 45-50 (or even less) percentile.
