AFM Exam General Technique

Hi Tutor,

I’m not sure if it’s appropriate to ask here. I want to ask about technical side of exam.
There are multiple workings options available (Excel, Word and BSOP). AFM questions are mixed of calculations and discussions.
Should I present the calculations in Excel and then explain the steps or copy them again in Word just in case?
And should all workings options be marked all at once? Do I need to click anything to save during the real exam duration?

I took SBR before, I had no issues (or there were but I couldn’t know). I did explain most steps in Word option. Recently I took a mock with StudyHub+ ACCA in their practice platform, all my workings in spreadsheet just magically disappeared. It might be their technical issues but I’m kind of worried it would happen with the real exam

Thank you for your time
