Dear Pravin, yes you can persue B.Com, if you are interested in commerce filed. Bachelor of Commerce (B.com) is a three year long undergraduate course that is evenly distributed into 6 half-yearly semesters. 

B.com. degree course is distinct from B.Com. (Hons.) as the latter allows specialization in various B.com subjects that students can choose from. 

That means in B.Com (Hons) you can choose any one subject that you had during your 12th as it will be easy for you to study and you can pursue your graduation in that.

All the best. 

Feel free to ask for any query.
