I have ADHD, wonder if thats whats causing this? ADHD really isn't much of a "handicap" when I am doing highly stressful studying - it seems to way more detrimental when I am doing leisurely study.
By the way the stimulants don't really help me - they just get me a buzz on occasion, and I blaze though questions making even more mistakes. Not to mention all the ****ty side effects.
