Failed by 3 marks..so you've got the hazard perception cracked. I will almost guarantee you that you will achieve around 47 or 48 when you do it again. You were probably nervous for the first time and lost some concentration. Just study a bit more and you will achieve. I pity the people who pass the first time by one mark or so..since it shows that they haven't learnt enough and shouldn't even have the chance to do the practical and pass by "luck". I passed my theory first time, but I scored 49/50 and failed on the question about some MOT document. Do it again, and you will pass, I will bet money on it.
