Just tell yourself that check rides will become a constant part of your life if you intend to become a professional pilot. Show up and do your best and if the examiner doesnt agree with your performance then you will do it again. No big deal.
You could also take the advice of the previous guy, but if you are going to be a professional someday then you had better not study at all and drink a dozen beers the night before, then wake up late and show up to the exam in the beer stained clothes that you were in the night before.
A true major airline pilot doesnt study for anything unless they are compensated with hours of pay for the effort. Any UAL pilot will tell you that it is the companies responsibility to insure that the pilots are trained and are able to remember what they are supposed to know. "If the union wanted us to study then they would have paid us for it." UAL pilot
Remember the airlines love incompetence. The entire system is designed to accommodate the lowest common denominator. The development of a smug I don't care attitude is key to a happy career of avoidance and denial. The people who care too much and put in effort usually burn out by watching all the misfits and screw ups skweek through another captain check ride. Don't let that happen to you. When in Rome become a Roman.
Best of Luck,
