I think exams are like one of the few times where I actually study for hours. But you know it’s cool, I find that what helps me study is writing out things and even saying them out loud as I write them. It definitely helps me, for sure. Who knows, it might even help some other people who might struggle with studying notes and things like that. A good piece of advice is: try to stay come, if you get frustrated, walk away from what you were doing, have a glass of water or maybe read a book for a little bit, and once you feel more or less calm, sit back down and get back at it. Happy studying!
