I would recommend taking up some INFS courses so maybe INFS1602 and INFS1603. Then take 2 of the core courses from the following list:
ACCT1501
MGMT1001
ACCT1511 vs ECON1101 (If you are taking ECON1101 you can do it in Sem 1 but if you plan to take ACCT1511 instead, you will have to wait till sem 2 as you need to complete ACCT1501 first)
ECON1203 vs MATH1041
Check this out. If you already haven't found this site or figured it out, you have to enrol in all your business core courses for this semester. I'm doing Info Systems (Co-op) myself.
