You mean BScIT, and you'll need to contact your faculty. Since the enrollment process has ended for local students (and you didn't apply for it) I highly doubt places will be left. This is especially difficult because you're going from just the IT faculty to the IT and Business faculties. This means Business needs to confirm that there are places in the BBus classes (for combined degrees) available to you as well, which I also doubt.
Still, there's no harm in trying! Contact the faculty offices for IT and Business.
