I think you'll do fine. To be completely honest, those scores are higher than what I've recieved before in practice exams.
The biggest thing you can do for yourself before your exam is relax and trust in your preparation. If you come to the testing center tense and nervous, I firmly believe that you quickly lose a lot of what you learned and the snowball effect happens. You begin to second guess your right answers, causing more stress and tension during the exam, creating further problems.
You put the time in studying and preparing. So enjoy yourself. Watch a movie that helps you relax. I prefer mindless comedies, for example. Maybe go for a walk if its warm where you are and clear your thoughts.
If you have an early exam, make sure you wake up with plenty of time to get yourself ready and fully wake up. If you have one that's later, try not to do too much to cloud your mind during the day. Occasionally think of concepts related to the AUD material you studied to make sure that you keep your mind geared that way.
Make sure you get all the rest you need both mentally and physically.
Dress comfortably, and in layers. It might be cold in the testing center.
…Also be sure not to drink a ton of coffee before you head to the exam.
Best of luck, but I'm sure you'll do fine.
