The higher I get in mathematics the more I'm noticing there is little to no extra time for thinking during an exam. If the insight doesn't come immediately you're basically screwed, since even with lightning-fast logic, you're still not likely to complete the entire exam in the allotted time. I've actually always looked down on people who claim to be "bad test takers" but I think I'm beginning to sympathize. I used to say (agreeing with Tosh), "oh haha riggghhhht...so you don't do well at the part where they ask you what you know?", then laugh derisively. But it seems the tables have turned! For instance, today I took a linear algebra exam where nobody finished. Okay, that's fine. The curve will be generous. But at the time, my mind was under serious pressure and I screwed up things I thought I knew, stuff that should be easy. Does this just mean I'm actually not as prepared as I should be, or are there things I can do to improve the speed of my rational facilities? I know a lot of people suggest brainteasers and stuff like that, or just practicing a lot problems, but is there anything else that may help?
