To be honest, towards the 3rd and 4th attempt, I stopped taking it too seriously. If I didn't feel like studying, I didn't. If I was tired, I didn't study. I strictly focused on the problems I knew tripped me up from previous attempts and worked those types of problems. I kept some good mental photos of problems that made me say "huh?" and I worked those. I also made a couple of essays by hand for problems 1 and 2 and worked them out in analysis software. In the end, just having done it before and knowing what to expect made it a lot easier. I walked in with 2 guys that were on their first try and I was outside dribbling a soccer ball and throwing a tennis ball against a wall because I wasn't nervous at all. Feeling comfortable goes a long way with your brain working
