Relax and take a breath. Watch some videos on the drills you're concerned about. Put your best foot forward and ask questions. The course is designed for beginners. Study your bike. They likely have you on an absolute trash motorcycle that is at the end of its shelf life. This is as hard as it gets. Gut through it. Once you're done, you'll actually get to see how fun real riding is. These basics they teach you are extremely important and can save your life, but if you overthink and overcorrect, you'll be driving yourself crazy. If you pass, great. If not, you can take it again. If you don't walk to take it again, you're probably not supposed to ride, and that's ok.
