B.Sc

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.

It depends on the stream you are from. If you are from science stream then it won't be a problem, but commerce or arts stream students are not advised to take up this course.

You should opt for B.Tech in CSE. It has better scope.

So, it will give you good options in future and also, many airlines would be coming in future. But time period for this growth is around 10 years.

B.Sc. in chemistry is 100 times better than B.Sc. biotechnology, although biotech has a great market abroad but in our country there is no particular job for this. You can go through biotech in M.Sc. if you want to be a biotechnologist, but I would suggest you not to take biotech.
