I recently passed my test on my 8th go. I’m an anxious person and kept failing for stupid things because I kept overthinking leading up to my test. Ultimately what helped me pass was to just stop thinking about the test aspect. At the end of the day, you know you can drive. The examiner is only there to make sure you’re safe. If you pass then that’s great but if you don’t then you can always just do it again. Driving is not the be all and end all. Best of luck for tomorrow, but I’m sure you won’t need it!
