Hi! I'm planning out my OAT study plan (I plan to officially start studying in December). I can handle doing physically extraneous tasks for a long period of time, but mentally, after 2 hours my brain won't be able to recall/remember information. It's a great thing to know that about myself as I study for my classes, but I feel like it might be a bad thing when I study for the OAT. Especially since the OAT is a 4hr exam, I don't want to do poor near the end because I don't have the mental strength anymore. So, how did you increased your mental endurance for an exam like this?
