I'm currently about 25% through the syllabus and it seems there are a number of times in J.Y.'s explanations he says, "If you're not familiar with logic rules for XYZ go back to that lesson and review it," but then I look at the syllabus and that lesson hasn't happened yet. Just wondering if it makes more sense to jump through all the foundational logic before doing practice sets that encourage us to know rules we haven't learned? Or is this intentional?
