If you ask me, here is the order of importance for day 1
1. Flows (Absolutely must know them cold)
2. Limitations (be at least 90%)
3. Memory Items (be at least 90%)
bonus is proficiency items but that’s really no big deal you have plenty of time for that after starting, and they aren’t touched for the first few weeks.
Systems you kind of just self teach along the way, that’s where you are kind of on your own although they touch on it a good bit. Don’t bother reading the AOM, it’s awful for learning systems compared to the guides and study Q’s.
Training here really is a pleasant experience.
