M.Com focuses on commerce, accounting, management and economics related subjects and prepares you for finance and accounting jobs in enterprises. MBA is a generic course on business management and administration and it focuses on functional areas of business such as accounting, finance, marketing, human resources, and operations. MBA provides wider options in different functions and various types of industries. Although you must do post graduate degree based on your interest area, I will recommend MBA with finance specialization for better career opportunities and growth.

In the majority of universities, eligibility criteria for M.Com is B.Com or equivalent graduation degree. Some universities also allow applicants from other streams like BBS, BFIA, BBA and BEE. You are not eligible to do M.Com because of your BCA degree. You are advised to do B.Com through distance, and then opt for M.Com.

Only having a graduation or post-graduation degree is not enough. There are many candidates who have a graduation degree, but they don't have the required skill. So we need to acquire necessary skills too.

You need to pursue M.Com on distance mode.
