I went to school in San Antonio with a guy named Bob (not his real name, obviously). Bob and I both took the LSAT at the same time at a school outside of Houston. Because Houston is a long way from San Antonio, Bob thought that he’d save some driving time (and thus sleep) by staying at a friend’s house in Houston the night before the test.
On the morning of the test, Bob started driving down the Tollway with his cup of coffee, and running through LSAT questions in his head. About an hour later, Bob realized that he’d been driving in the wrong direction. He quickly made a U-turn and drove over 100 mph back the correct direction, and eventually, realized he hadn’t brought enough money to keep going through the tollbooths. So he started just driving up the tollbooths and telling the operators, “You’re letting me through.” I think they could sense his desperation, and since they didn’t have a vested interest in collecting his money, they all let him through. When he finally got to the school, he sprinted up to the building, literally just as the proctors started letting people into their rooms.
At this point, I ran into him and we laughed a little bit about what a tough morning it had been for him. I hung out a little while and tried to get him to calm down (the poor guy was sweating like crazy and pale as a ghost). But after a few short minutes, we had to go into our rooms and start our tests.
After we finished, I found Bob and told him, “Oh, you wouldn’t believe how tough I had it all through the test. I was sitting right behind this person with a horribly stuffed up nose, who sniffled and coughed through the entire test.” Bob shook his head and said that about 5 minutes into first section, the person behind and to his right had puked all over her desk.
So my advice would be “Try not to be Bob.” Of course, Bob got a 172, so maybe not.
