Hii Deepak!
B.com Hons and b.com courses are slightly similar to each other. The only difference being in the depth of the subjects taught in the two. B.com deals with general studies of all the subjects related to commerce. But, b.com Hons gives you a chance to study the subjects in details and get a specialisation in a subject. It also includes some extra subjects such as corporate accounting, corporate law, management, e- commerce, computer application etc.,
Hope this helps.
Good luck!
