Rolling back in to add, don’t dwell too much on answering EVERY question. If one stumps you, make sure the other one’s are answered thoroughly. The scorers are trained to score based on quality and not quantity, so if you are unable to answer one question, you won’t be marked down for no answering it.
Each module thing is worth 9 points I believe, but that doesn’t mean each question is worth 3 points. You’re scored on overall response and quality.
You want to answer all the questions of course, but if you answered 1 or 2 solidly and missed the others, you can still score well!
