Exam

MAT exams conducted by AIMA (All India Management Association), usually take place four times in a year:
1. September.
2. December.
3. February and
4. May.
So, before 2 months of the exam, you can go online on the website of AIMA and get yourself registered.

For ethical hacker, you need to take some other specialisation course. It will be a certification course. IIT JEE is required to pursue engineering in different fields.

With above 600 score in MAT, you can apply to any b-school. You should be prepared for GD/PI.

You have a good chance, prepare well for the GDPI.

It is a very low score. You need to appear for other management exams like XAT, CMAT or ATMA and give your best in those management exams.
All the best.

It is a very low score to get a decent college. I would suggest you to appear for CMAT exam as well.

You can try for:
1. ITM – Mumbai.
2. Balaji Institutes – Pune.
3. MIT - Pune.

I think, you should go for professional certifications. MBA from an average college does not benefit much. You can enroll for professional certification in finance, marketing, etc. to get ready for industry demand.

You should start your preparation. You need to cover NCERT books, and then go through the previous year question paper.

IIT KGP provides admission through CAT. The percentile requirement is higher for general category an approximate of 97-99. Then you will receive a call from the college for further rounds.
Best wishes!
