I think the practical all depends on the person judging you! I didn't pass first time and I think it was harsh what I failed on, but the one I passed on, I was more comfortable with the lady and although I kept doing this really stupid thing, because of nerves (all of a sudden, every time I stopped, I kept forgetting to put it back in gear before pulling off!! Duh!!), she knew it was nerves and I passed through it.
I think the biggest problem is nerves, I took lots of kalms and rescue remedy to try and calm me down!! Good luck! x
