Overall, I think this unit was fairly easy for me to understand. There wasn't too much problems for me other than a few things. One of them using Proof of Contradiction to prove a problem. Such as the Knight and Knave problem. Im a bit confused on how to use indirect and direct reasoning. Hopefully i'll get this cleared up tonight. I also need to focus a bit more on operation on sets. Understanding what areas the sets are talking about. Other than that, I'm feeling pretty confident about the test.
Good luck to all !
