Feel free to come up with more queries.
All the best.

You would be eligible through GATE score and not CAT.

Hey,
You are eligible, but you won't be able to get admission in a good college or even in an average MBA college. I would suggest you to reappear for CET. Besides, that you can appear for ATMA, MAT, CAT, IBSAT exams which will give you more scope to get better colleges.
All the best.
