Hey there!

The main difference that arises in the ISC Commerce subjects and CBSE Business Studies is of the course content that they both comprises of. Although the former one comprises of the main subjects that are associated with the commerce field, the latter one includes few extra subjects which enhance their overall understanding of the commerce environment.

As far as career opportunities with respect to both of them are concerned, they are equally distributed.

Both are good with respect to career path and enhancing a person's whole ideas about the related subjects.

Good Luck!
