I stupidly chose question 3 (at first glance this looked better than Q4 I had exam brain clearly!) by the time I had read through the scenario and tried to work out part a to no avail I did contemplate switching to Q4 but with 25 mins left this was a no go!!
Q1 & Q2 were ok I also got carried away on Q1 two and a half sides for 9 marks!! Exam brain again!
Will be a hit or miss on passing due to Q3 I left part a outcompetely! I agree the examiner needs to just say what he wants instead of talking in riddles that wouldn’t happen in the real world!
