I have to choose between CSE (preferred branch) at MIT Manipal and chemical engineering at NIT Surathkal or BITS Pilani - Goa campus (preferred colleges). What should I choose?

The best option for you is to take up an M.Sc. degree at the BITS Pilani Goa campus. The M.Sc. degrees that are offered are Maths, Physics, Economics, Biology, and Chemistry.

If you are confused about the stream, let me give you a clear idea.

• In the first year, the students get to know all subjects. 
• They get an opportunity to interact with their seniors from other streams. 
• Eventually, they can opt for the B.E. degree after the first year ends. 
• The most difficult to get is Computer Science as the student is required to maintain a CGPA of 8+ in their first year. 

Pros of choosing BITS:

• Of the three options, BITS Pilani is considered to be the most reputed.
• Foreign Universities recognize BITS, IITs and some NITs. This will gives you a slightly better chance of getting an MS to admit.
• The network of BITS alumni is very strong. You can easily get referrals from the top firms for jobs as well as internships.

Cons 

• If you want to opt for Chemical Engineering as your B.E. degree, a CGPA of 5 will be enough but if you want to opt for subjects like Computer Science, you will have to acquire an 8+ CGPA.

Therefore, going for BITS Pilani is concluded as the best choice. One should not decide in haste.
