Study. I'm sure you have a few more exams left, and if you're like most lazy students, you're probably watching tv shows and derping on facebook.
I don't know what you're expecting for an answer... but some students 'shadow' second year programs they didn't have the marks or requirements to get in. What this entails is taking courses that are required for that degree (the ones that don't have the "studnets of level 2 commerce" preface) while not actually being enrolled. You can then re-apply the semester/year after that again, should your marks improve.
Are you really sure commerce is for you?
