It's great that you're trying again!
I recall when I moved from 1st year to 2nd year, UBC made us apply for our preferred majors (3 choices) online to prepare us. Do you have that too? If so, it would help to know which major you have as a back-up (assuming Pharmacy is your ultimate goal). It would be best to satisfy as many prerequisite courses as possible within your major, while building up your Pharmacy courses (like MICB202, ANAT, etc) at the same time.
Pharmacy electives aren't used in the admission average btw. Only prerequisites to Pharmacy and courses in the mandatory part of the Pharmacy curriculum are used in GPA calculation.
