I think your average is good to consider in the internal transfer. However, do you have enough equivalent courses that are the same as Business 1 students taking? If you have all these courses: ECON 1bb3, 1b03, One behavioural science unit course (Psych 1x03, anthro 1aa3/1ab3, religion 1b06, pol sci 1g06, sociology 1a06), computer science 1ta3/1ma3 which i believe is equivalent to computer science 1ba3, 3 unit calculus course (6 unit calc if gr12 calc&vec is not completed) and 3 unit of stats (gr12 data mgmt if not completed), Plus if you dont have 6 unit failed course, then you're more likely to get into commerce. Good luck
