AFM – Format of Answers

I’ve been attempting some questions for the upcoming AFM exam on the exam platform and there are some parts of questions that I don’t know whether I should be answering it in the excel or the word part.

For example, if in a report question I write the report in the word answer section, can I refer to an appendix which is then in the excel part so I can do my calculations more quickly and just include a table to summarise in the word section? Or will it read better if I include the calculations in an appendix in the word document?

Thank you in advance!
