Okay, for the combinatorics unit, my muddiest point are the circular permutation and the card problems. I freaked out when I see these kind of problems and don't know what to do. I am really confuse when to use the pick and choose formula though I know the rules. Even though it seems like an easy question, I totally messed up. I simply don't like this unit. =p

Good luck everyone!
