F4 CBE

I note from the specimen paper on the ACCA website (for Dec 14 and CBE exams) that the questions at the bottom section require some form of narrative. Is anyone aware how this is marked by ACCA? i.e. it would appear that once the CBE is completed it is unlikely that a result can be given instantaneously due to the fact that a human will be required to review the answers. Any assistance/clarification on this matter would be much appreciated. It would appear they are “only” worth 30 marks – so perhaps a provisional result is provided based on the responses to the multi-choice questions (just a thought)?
