B.Com Scope

You have following options on completion of B.Com degree:
(a) M.Com
(b) MBA/ MBE/ MIB etc.
(c) MCA
(d) LLB
(e) Masters in Social Work.
(f) Master in Mass Communication

You can do CA, CS, CMA and also MBA. It's all up to you.

You could try going for MBA after your Bachelor's degree or you could go for M.Com. Both the degrees are of equal value in the market and if performed well will take you to great heights.

First, complete your B.Com then go for MBA because the course level is same of BBA or B.Com. Then after MBA, you will get a job.

I would suggest you should explore the short courses available in India like studying a foreign language. It will surely be beneficial and economical as there are a lot of different options available here. This will add up to your CV and also you can start doing an internship which will strengthen your resume

Go with M.Com instead of doing other courses.

Some short term courses (PG diplomas) are:
Search Engine Optimization (SEO)
Search Engine Marketing (SEM)
Social Media Marketing (SMM)
Email Marketing
Inbound Marketing
Growth Hacking
Web Analytics
Mobile Marketing
You can also pursue the PG as in MBA in digital marketing

Both have an equal scope. You choose for any between DU & GGSIPU. And both B.com & BBA have also equivalent scope.
