Full Time

Hello Atik! Yes, you can pursue an online or classroom based certification course in the Digital Marketing field if you are really interested in doing so.

I think instead for going for a course, you should join a company and start working as only then you will be able to gain sound practical knowledge, pursuing a course after MCA won't help you much.

It could be possible but very difficult. B.Tech is a very demanding course to pursue and additional course will be very tough.

Full time MBA is a better option in comparison to part time MBA because:
(a) Better learning because of case studies, workshop and other techniques
(b) Campus placement can help you to get better job.
(c) Opportunities to interact with faculty and fellow students.
(d) Opportunities to develop leadership skills.
(e) Summer training to practice learning while undergoing studies.

Two degree in any way not permitted at a time in the rules in India. It is surprising that you are interested in two different career direction at same time. Think before it because it is related to your life than take any decision.
