Now I Completed M Com (F/A) & MBA (F/M). First I am finding for one good job and I want take one new course, which course is better for my future?

What i see in your studies is that you are from finance background. so you should go for improving your computer skills and search for financial institution who can offer you better job opportunities.

For me its depends on your decision. Because you know what is the best choice on your future

Your course selection should be based on your interest as well as the market demand. 

Its more up to your skill level which wanted to improve to accomplish your next level of the career.

Audio visual and Vedio Conferecning 

courses like data base/pitchtree/ which are very important for yours job skill

masters of commerce is the better and MBA is also good  

Chartard accountant is the best course for your future

I would ask him/her to meet expert in Commerce and  Business Administration. 

You can go ahead with either a CPA (USA) or with CFA.

You can take a certification course in Accounting, Management of Financial Analyis.
