Well i Failed my first time so dont worry, even my second was a bit sketchy i got 5 minors for speeding and 4 for realising i was speeding and slowing down too quickly. My advice to any instructors is too not make people have too many lessons because people get bored and start picking up bad habbits. My instructor was a twit stupid Jahova's witness do gooder. (no offence to any Jahova's witnesses they just tend to do things slightly differently either that or he was scamming me by not putting me in for my test)
the thing with mine was i was paying him to practise and i had , had enough so i just said iam doing my test end off and he didnt say nowt so i think he was just trying to get more money out of me
