MBA Standard: Pre-MBA Courses

Asking current students/alumnus of the MBA Standard Program. I’ll be starting in the MBA Standard Program in the next trimester and planning to take two subjects first. I wanted to ask for recommendations on what subjects are ideal to take together, or at the very least if there are two subjects that are not ideal to take together?

In addition, I also wanted to ask if there’s also an ideal way to space my schedule out. Do you recommend leaving at least a day before your next class or does it not really matter as much?

Some additional tips are also welcome. Thank you in advance!
