MBA degree is very much in demand now-a-days. So, you must take up MBA.

Both M.Tech/MS and MBA are good career options after engineering graduation degree. M.Tech/MS will make you a specialist in chosen field and you can make career as a technologist. You may seek admission in M.Tech/MS if you are technically inclined. If you are not technically inclined then you may opt for MBA and become a generalist. Currently scope of MBA is wider but slowly industry has started paying good salaries to technologist also. If you can afford MBA & MS abroad you may go ahead. You may evaluate USA, Germany and Australia universities for higher education.

You can pursue B.Sc, and prepare for NEET 2017 along with it. It is up to you.

Students who have passed 10+2 board examination (any stream- science, commerce or arts) are eligible to pursue this course. Minimum marks criteria may exist in case of some institutes (usually around 50% aggregate marks).
If you have the above eligibility then you may take admission in B.Sc in animation.

You need to have a graduate degree to pursue MBA. You can opt for either of the two streams. You need to focus on your studies and score well in them.
