tHANKS GUYS…I did definatley take my test in an artic with a boxed trailer on the back… so i shall have to wait until the licence comes back in january…The reverse was hard on my lessons i could not do it properly on the lessons and on the test i could not do it… so how did i do it… well i started at the two cones and sat there for a minute and slowly went passed cone B…then i shunted it forward to get the trailer and unit straight and kept the blind side barrier as a guide as it is a staight barrier and went backwards at 0.5 mph taking twenty mins to get it in the box…safety first… 
Dont worry goofball my examiner done the exact same and i was worried too so i phoned the test centre first to make sure it was right. you will defiantly get your licence back with your C+E on.
