You have to listen quite intently to write notes for his class, especially if you're in higher-level maths (like IB). Fugu is incredibly capable but his teaching style might leave you in the dust if you're not up to speed. He doesn't post many supplementary support worksheets so it's quite hard to self-teach especially if you're behind. But don't be afraid to ask for help if you've given work questions a try or know what you're confused about, he's super great at helping you answer example questions (but he may not explain things differently in a way you understand).

Study for the tests Listen in class Take organized notes, all the information Fugu gives you is really good to know Do the workbook even though he doesn't assign it.
