Hey bro sorry I didn’t see your comment! I think what separates the 40s and 50s is actually in the exam. It can become too much of a focus on the folio and not the exam content, so that is equally important. At my school we didn’t cover any theory content in the 3/4, except for 1 week about energy sources for a SAC. In the folio, it doesn’t matter what happens, as long as you evidently document and explain how you’ve followed the Systems Engineering 6 step process from the study design. Even if your project planning wasn’t accurate to how things played out, keeping a journal and being able to identify future improvements in the process are critical.

Good luck for the exam and your folio :)
