For our school, we have the students trying out sign up for what events they want, but we don't have build event tryouts. Any lab portions are also eliminated.
However, here's two aspects where I think our school might differ:
1. Tests are written by A-team students. This is because in our team, anyone who was on A-team this year does not need to try out again next year. However, people on B-team do have to re-tryout. Which brings me to my second point.
2. Students are not allowed to use cheat sheets, binders, etc. In fact, some events don't even allow calculators on tryouts. I'm not entirely sure why, but my thinking was this: three middle schools funnel into our high school, but only one of them has a Science Olympiad team, and it's a pretty decent one too. In addition, you have old members trying out again. These people likely already have access to notes and materials, and if we allowed them to bring in these notes they already have while everybody else has to make their own, that would be an extremely unfair advantage.
