Hi I'm a year2 commerce(3502) student and I've changed my mind to major in actuarial & finance this year. However I didn't do the actuarial courses which were required in year1. I'm now taking math1151 in this semester. As I know, there are no summer courses for actuarial, so I might need to defer my uni study by a year (i.e. 3+1= total 4 years). If that is the case, can I change my commerce single degree(3yrs) to comm/sci double degree(4yrs)? so that i wont waste that extra year? Thanks a lot and advices are appreciated.
