Yikes tomorrow is the day! Just going over circled questions in destroyer, chads quizzes, and reading through alan's notes. But I didnt have the time/money to get math destroyer, but ive studied and timed myself with the achiever/regular destroyer questions and am decently comfortable except for permutations. Anyone know a good site for learning them? Chad does a good job explaining them but the questions with multiple probabilities and factorials get confusing. AHHHHHHHHHHHHH.
