After completing a B.Com in CS, several higher educations are available that you may need if you are eyeing higher careers. For instance, if the area of interest is commerce and corporate governance, then one can pursue an M.Com. If someone wants to pursue management, then an MBA with finance, marketing, or HR would be very useful. In addition, professional courses like Company Secretary (CS), Chartered Accountant (CA), Cost and Management Accountant (CMA), and Certified Financial Analyst (CFA) can fetch lucrative career prospects.
If one of your inclinations is towards law, then you may opt for an LLB (Bachelor of Law), which suits fairly well with corporate secretaryship. Another way around would be to do PG Diploma in finance, taxation, or corporate law. A number of universities offer specialized Master's courses on International Business, Banking, or Entrepreneurship. The right path would depend upon one's interest: finance or management and law or corporate governance.
