B.Sc

Hi Aman,
You are eligible to pursue MCA. MCA is a 3-year professional course in computer application. Various good institutions offer MCA. For any query, do reply on the same.

No, there is no such legal process for doing two regular courses at the same time.

Biotechnology has more scope than microbiology. You should opt for B.Sc in biotechnology.

The minimum specification for B.Sc in animation:
An i5 processor will handle many different types of artistic projects effectively.
At least 8 GB of RAM
A 17-inch laptop
programs like: CorelDRAW, Graphics Suite X5, Adobe Illustrator, Art Rage 3.5, AutoCAD and Xara Designer Pro.
Suggested:
Asus ROG Strix 17.3" Laptop
Acer Predator 17.3" Laptop
Lenovo Z70 17.3" Laptop

Don't go for B.Tech as today B.Tech is just a money making process for most of the colleges. After spending 4 years, you get nothing. If you want a job then do a job oriented course with SIPL training institute, they will ask you 12000 Rs but only pay 10k to them, you can choose other institutes too., according to your choice or simply do B.Sc. It is cost effective. I am saying this because I am a technical graduate and I faced the real problems after B.Tech.
