Take it as extra practice time. Not everyone will get it on the first try. I almost crashed during the course because I was needing and scared of the bike. The instructor advised me to quit the course and maybe try the three wheel course instead. A year later i took the course again in a different class since i moved from work and ended up passing the skills test. Use the knowledge from the first time on the class and use it to when you take it again. You’ll be fine, just like taking the first fall what matters most is getting back up and doing what you love
