Dude since you are from Mumbai, check out BSE's website:
Bseindia
The stock exchange offers several classrom-courses of short duration like Basic Course on Stock Markets, Derivatives, Mutual Funds, etc. You can pick from the list and go attend these courses at a nominal cost. A few courses are followed by certifications, which is optional. If you complete the certification also, it adds value to your resume.
In fact, in one of my interviews i was quizzed in detail about the Derivatives certification that I took some time back(BSE's Certification on Derivatives Exchange)
Hope this helps
