What would you do?

When I was in school I did just about everything well, but my curved backing was hit or miss. I wouldn't trust the truck to do what it was supposed to, and I would over correct. I missed this part on road test and had to come back and pass it to continue the rest of road test. It sounds like you are doing the best you can and all you can to pass. Remember that you will always have to overcome obstacles to get what you want(especially in trucking). You've gotten some good advice about eyes open, mouth shut and if there really is a need then assert yourself. Don't over think it, don't stress it so much. This will be a faint memory once you get out on the road, stay determined and don't worry about what you can't control. You'll pass!!!

 

Backing simply takes practice. One of these times, you'll just nail it.
