F7- MCQ - Answer format in real exam

Hi, I am re-appearing F7 after a long time (the format has changed since I last sat F7). My question is, will MCQs need to be answered on the front of answer sheet (first page) where you fill the circle so the automatic scanner will be reading the answers? OR will these need to be written on the answer sheet like rest of the questions , e.g Q1- a, Q2-d etc? If the dots need highlighting, I assume the calculations can be done on the answer sheet starting from blank sheet, of course these will not be marked? Thanks Vish
