Third time lucky, many pass on the third time as we all suffer with nervous at times, you will do it this time. This is your time, you will smash it.
Try and relax, they always say imagine someone you are nervus of as naked but not sure if that works myself. Don't let nerves hold you back and remember you can have up to something like up to 20 minor faults before they fail you so this time, be confident, head up, forget the examiner is there, imagine its your mum or dad instead or someone you like in the car with you and give it another go.
No pressure, nothing to be nervous of, you have done it before so lets face it what's the worst that can happen? you fail again? and in that situation you can always do a fourth or fifth test if you need to anyhow, so you have absolutely nothing to fear. just go in have another go, give it your best shot.
Sometimes we just need a bit of luck on our side in life, you can clearly drive, you got this,
Routing for you, good luck.
