B.Sc

I don't think so. In order to join MCA, a candidate need not necessarily be from BCA. In order to join MCA candidate must have maths in +2 as one of the subjects. You may feel some problem with programming language.

Dear Viral,
As per my knowledge, None of the colleges in Gujarat are offering B.Sc in economics.

Dear Govind,
B.Sc in nautical Science is a niche course to pursue. After completion of the course, you should undergo the 1 year long sea service. After the sea service and clearing the subsequent oral examination, you can obtain the second mates Foreign-going Certificate of Competency. This certificate will enable you to hold the post of 'Navigation Officer' on merchant navy ships.
All the best.

Thank you.

B.Tech in IT is good but in foreign countries, B.Sc in IT is popular. But in India, you should do B.Tech in IT.

B.Sc in economics will be a good option for you.
