It's the management and validation that's giving us a headache!

Not easy is it Joe. A tip from me is: Try to go for the most correct answer when 2 answers may be correct. Its sometimes a matter of trying to give the answer the assessment body is looking for. Another tip: they give you 4 answers on the multi choice. Only 2 are going to be correct or near to correct, disregard the other 2 answers and have a guess. If you get it wrong the first attempt it has to be the other answer on your second try.
