When I took the GeoMapping in its first year, we didn't use sheet protectors, as they only slowed us down, but that's our opinion. Both partners ever needed the binder, it was easier for us to just rip out the page than have to open and close the rings over and over. We also had a huge binder with a TON of information and past tests, so opening the rings was just a pain.For making a binder for this event, are sheet protectors useful, or will they just take up space? I used sheet protectors in Fossils, but I don't know whether tests in this event will require as much speed as in Fossils.
Also, when I write tests (I've written a lot for PA), they are always quite long. Usually long enough that if BOTH partners know what they're doing, they'll finish. This helps really separate the top from the bottom. As someone who took the event, it always helps to assume the test is this long, so you want to utilize your time, and binder use, the best of your ability to ensure you can get as much done to the best quality.
Just my two cents.
