This reminds me of a drill I did/do with students very late in the course. I pull out a logic game and tell them that they have five minutes to do it. At first they panic. Then they start working the game and almost every single one of them knocks it out of the park. It's a really easy game. The next class, I have them do 20 LR arguments in 20 minutes, some of which can be done in a minute each and some of which really can't. My point in both cases is to show them what it feels like to really demolish something and that they can, at this point, do it. It seems to provide a confidence boost and a change of mindset.

The secondary point is to recognize which questions are easy and you'll do in under the average time, and which ones are harder and you really do need to take more time on. A lot of people, late in their studying, are panicking about more or less every question. But they're not all hard. You do know the answers to a good number of them pretty quickly.

But practicing doing well will make you do well more often, and that's the main point.
