The course fees for B. Ed. Can't exactly be said here as the college does not have a website I guess. You can contact the college directly, the contact details of the college are given in the shiksha platform, which I think would be rather helpful for you and better of you to ask the fees of the program you have intended to enroll yourself in

It will be more convenient to teach commerce since you have been a B.Com graduate.
