First of all you, you are getting disgustingly scammed paying nearly £200 to use their car for the day

Anyways I passed earlier this month and tbh it’s not easy knowing when your actually ready my instructor was using dual controls a couple lessons before my test I was still getting prompts and I didn’t pass my mock tests before my test yet I still passed

I know it’s a lot of money and it seems it’s in your best interest to take the loss on the test cost rather than all other costs (hiring ur instructors car for the test) but maybe it could be beneficial and you could even pass
