Typically, I rewrite my notes, draw pictures, find youtube videos, anything visual basically. If I can't see how or why something works, I don't understand it (this is why I hate chemistry, everything just seems to happen just because). I've always been a biology major, but was toying with the idea of graduate school as opposed to vet school for a couple years. During that time, I significantly increased my GPA. I still study the same way, and I definitely try to make sure I have at least one day a week where I don't do anything school-related. That helps for sure.
I do think I have horrible test anxiety, but so do a lot of people, so I didn't think it would be legitimate to bring to the student resource center to be able to take tests in a quieter setting. I am like you, lailanni and every time someone gets up, coughs, squeaks their chair, etc I am totally distracted. Sounds like I can and should pursue this route and not have to feel as rushed or distracted.
SV88, that doesn't sound silly at all! I sometimes do give myself mental pep talks during exams and tell myself, "you know this stuff, just write it down." But then I start beating myself up if it doesn't come to me and I think about all the other students taking the test that probably know the material and make As and have a 4.0 and why can't i just be like that, etc.... Ugh! I know that's totally nonproductive too.
It sounds like maybe I should talk to the student disability resource center and find out about taking tests in a different, less stressful location.
