This is a summary I made while repeating for POC. Our POC exam was open books and honestly, I'd say it is better to kind of know some concepts by heart or at least compress your or my summary further so it gets easier to look it up. The POC exam consisted of questions we had to answer with arguments that contained the learned concepts. I'd advise you to pay attention to the lab session and just copy what they're saying, even if it doesn't make sense to you. Just argue "like them" and don't question stuff, this will make you avoid confusion. (This is just a me thing, learn however you want to learn.)
