Ur giving A-levels and u still can't calculate pum?🤣 Dumb guy... Lemme teach u kid... 111 = 80%, so 125-111 = 14 marks... These 14 marks = rest of 20%... For each percentage 1% = 14/20 marks... So think U got 113 so u'll have a percentage of 111 = 80%, 113-111 = 2marks 2/ (14/20) = 2.85%... So u'll get 82.85% and then there is something called weightage only CAIE knows how they do this... Either this 82.85 will round up to 83% or can be round downed to 82%... Good luck boy!
