Hello,

First of all there's no specific aggregate set for MAT, one needs to have passed graduation in any discipline from a recognized university.But, yes different colleges accepting admission based on MAT scores might have different eligibility criteria that may vary.

You can go ahead for preparation for MAT, you have to balance your work as well as preparation, there are many people who're working yet preparing for different entrance exams. So, you have to make your plans accordingly and devote time in the similar manner.Also, you have advantage here as MAT is conducted four times a year.

Hello Abhijit, yes, it's no big deal to prepare for competitive examinations while one is working. There are many people who have cleared exams like GATE and UPSC while working besides. You just need to have a good routine with proper time for both work and study and you should increase your time of study during weekends because there would be holiday. Yes, you are eligible for MAT, their is no minimum % for MAT but check with your institute first because the eligibility percentage differ for each college.
