This time next week I would have done the driving test (and hopefully have my P's)!!

I'm pretty anxious about it. I had a driving lesson last week and it didn't go as well as I was hoping. I hadn't had a lesson and a month and I honestly forgot how to properly reverse park/3-point turn when I did it the first time. I also still need to work on parking in car parks.
I drove around the test area with my dad last weekend and it ended up going really well. He's been making me drive everywhere at the moment to try and get more comfortable. I can drive safely and at this point I probably have close to 200 hours (we stopped writing them in). However, I'm a bit worried that I'm going to get nervous during the test, make a stupid mistake and fail.
