Choosing classes

Hey everyone, I’m enrolled in psychology at U of C and I’m having a bit of difficulty choosing my courses. I’ve reached out to an advisor but it might be a while before I hear anything back. I currently only have one required course and 4 open options. Am I required to take all 5 courses in a term? Or can I leave “spares”. My other question is that my end goal is medicine, I’ve looked through the recommended courses to take and was wondering if anyone has any opinions on how many of those to take per term? Or if any of them are more important? Thankyou
