I'm sure you'll do just fine
I'll reserve my driving test story until after you take yours haha - I did pass, though. And I drove in Montana in the middle of winter 2 years ago on the way from NJ to WA. Not that I EVER want to do it again but I feel more confident on the roads now. I've lived my life in big cities (NYC, London) so I never bothered getting a license 'til I moved to NJ when I was 27. It is much tougher when you're older, I think. Since you become aware that you're not actually immortal.
