It's a dangerous way of doing things by marking the answers on the question paper. Many a pilot has gone before you and not had time to transfer the answers over at the end or done what you think you have done and put them in the wrong boxes !!.
Always always mark the answers on the
answer paper, if you are unsure of a question, put a discrete mark next to the number on the answer sheet and carry on, that way you don't end up putting the answers down next to the wrong question numbers, then at the end you know which to go back to straight away and can then rub out the mark you made once you have finally answered the question.
Worked for me, and I've passed them all now, got the results this am.
