You have options of doing degrees or courses such as M.Com, MBA, MCA, PG Diplomas, industry certifications, CFA, CMA, LLB, etc. 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.
