F2F Theoretical Driving Course (TDC) Exam Tips

i'll be taking the 15-hour TDC and there's an exam every after module discussed. kinda worried since 80% is the passing score for these exams, and you'll pay addtl 600 pesos in case you fail.

just want to ask for tips like what should i expect? is it hard? do i need to take notes during discussion? also, what kind of questions do they give, multiple choice or another type?

any tips & advices are welcome since i'm worried i might fail lol. i'm confident i can answer road technicalities but a bit worried with law-related questions.

ps. im taking tdc at pajonic driving school
