Been telling my self all these things for a while... Still has to sink in yet... I just need to forget there is an examiner staring right at my every single move and focus on what i'm doing.
Really helped that i've had an amazing instructer, bonus is he's only two doors down lol
Most important thing to remember is they're not really looking for good driver but a SAFE one. You're a beginner and it's experience that makes a good driver.
Mirrors, keep looking at them ALL even if you're not checking whats in them (you should be). If you make a mistake, don't panic, think what you should have done and then if the examiner asks, you can show you were aware while driving.
