Yes, there can be, but very less, in comparison of regular studies. Good companies prefer to hire candidates who have done regular courses. I would suggest you, to attend B.Sc. Classes physically rather than going for distance, if possible for you. In fact it will also be good and helpful for you, to understand the subjects and their concepts if you physically take the classes.
