Another thing that really helps me is repitition and continuously studying, not just when there's a test coming up. I originally started doing this for A&P when we would have to memorize all the muscles or bones or something but I've found it works really well for me in my nursing classes too. After we go over something in class I'll read over and review my notes every other day (or every day if it's something I'm having trouble with). I'm not trying to beat it into my brain and I don't spend a whole lot of time; just simply read over it to keep it fresh in my mind and making sure I understand it. Then usually by the time we have a test on it there's a lot less pressure and I feel a lot more confident. Hope that helps
