But I meant - do it over 2 days, but ask the instructor you know & like. Pay them for an “intensive” course.
My favourite instructor who I learnt for years with and have known since I was a baby is too busy to take me on again.
Have you had your instructor sit in on a test? Would that help, perhaps?
I haven't. Maybe that would be a good option for the future.
If it is anxiety leading to extreme nerves, can you ask your GP? Some are very sympathetic.
I have gone to the GP tons over the past 8 years. I do think my anxiety's getting better, for the reasons I detailed below. They've tried me on a few different drugs, and I've had CBT. But mostly, I've had a really stressful life, and they've just said my anxiety is due to that more than anything.
Do you fail on lots of small issues or major mind-went-blank stuff? People may be able to help more if you can be specific?
Major stuff definitely. In my last test, I was doing great - and the examiner said my manoeuvre was turn in the road. Fab I thought; easiest one by far. Next thing I know, I'm on the road hurtling towards a tree. I heard - THE TREE, THE TREE. Anyway, I got a dangerous. My driving instructors been teaching 20 years and he said he'd only had 2 people get a dangerous. Usually if you get that, they stop your test and drive you back themselves, or make you walk (depending on which car you did the test in). 
I don't know what happened there, I really don't. I'd never even been taught turn in the road, just did it casually and perfectly in every lesson, as it's not really difficult at all, is it?
Apart from that from what I can remember from the past few tests, I've got a major for pulling out too quickly and lots of minors for hesitation. I just overthink things and so I can't quite get the timing right for stuff.
But surely all these kinds of things will help if the anxiety is beaten out of me 5 hours a day for a couple of days?
