I had to do it as my 2nd and 3rd job choices were the RAC and AAC. It would be a piece of Pi$$ for someone with perhaps more intelligence than to be in the british army. I found it sh!t hard and didnt get the score needed for the AAC but met the score for the RAC.
Waste of bloody time really as i still want to go into the infantry, but if i decided to switch from the infantry to the RAC between now and starting basic i could.
the hardest part was the algebra, i couldnt make head or tails of it
