b.com vocational : Sir what is difference between b.com (main) and b.com (vocational). And which is better and simple

Dear student,

B.Com. Vocational stands for Bachelor of Commerce in Vocational Commerce; if you choose to study this course, then, along with a commerce degree, you are also vocationally trained in some particular areas such as computer application, tax procedure and practice or advertising, sales promotion and management, travel and tourism, etc. The syllabi for the first 4 papers of each semester would be common as that for B.Com. 

B. Com course will essentially include general, corporate secretarial, accountancy, banking and even insurance. 

Which is better?

It totally depends on your career aspirations. If you wish to pursue M. Com or MBA, then B. Com is a good option. If you want to get into the logistics of commerce, then, B. Com Vocational is a good option. Good luck!
