No, but I have had blackouts from time to time during university exams (the environment and the people just make me nervous). However I wasn't well prepared, so the blackout isn't the only reason I didn't perform well. I haven't had any problems studying, I just want to make sure to have this part of the test taking covered. They are important to me because I don't want to repeat a whole year because I was nervous.
