To get your maximum PT score, the week before the PT test, do light PT. Your body will be craving to fly on test day. If you can’t do that, than do light PT two days prior. At a minimum, the day prior to the PT test, don’t do muscle failure! The goal with your PT test is to max it. Resting the day prior I believe adds a good 5-7 points to your PT test and muscle failure the day before can be the difference between pass and fail for those that don’t have strong PT scores.
