Not really. By the time you reach test day, you’ve done the work! Easier said than done, but I just recommend trying to go through your normal routine before the exam. Get up in time so you’re not rushed, eat a solid breakfast, etc.
During the exam, you’re not going to know every answer. There will be some wildcards in there that you could study for years and never stumble across. Don’t get hung up on them. The goal isn’t to ace the exam and many questions will be thrown out during analysis anyway. Try to keep a cool head and trust the work you’ve put in! Most people leave the exam feeling as if they failed and most of them pass- so feeling discouraged is normal. You’ve got this!!! 🙂
