The test you see on test day will already have a scale assigned to it. It does not matter how many people void it, bomb it on purpose, or score astronomically high because the scale is set. Those instances may affect some piece of the pie when the AAMC determines the scale for future tests, but there is no retroactive scale-changing. It's not a curved test (where as your success increases as that of others decreases) but a scaled one. 2 different things. Everyone who takes the same test is held to the same scale.
