I'm in last year of BCA. Should I do MBA or MCA?

This would depend on your interest areas and career aspirations. In case you intend to pursue a career in Technical / research / academics area then MCA/ M.Sc ( IT) is better. However, if you want to move into general management the MBA is better.

If you are interested in programming, and want to learn more then go for MCA. Else,if you want to work in management then join MBA. Both of these courses have high potential, it just depends upon your interest, you can do well in any field if you have interest and determination.

Hello, You can pursue either of this. If you wish to build a career in technical field, then opt for MCA. If you have an inclination towards the managerial structure, you can certainly go for management studies MBA. Choose the stream which is compatible with your interests.
