I don’t think the peculiarities of the Pearson spreadsheet can be an argument for not doing well. The CAS gave us access to the Pearson software at least two months ahead of time. I spent the last two months doing practice problems in Excel but forcing myself to not use the shortcut F keys, especially F2 and F4, which I use all the time. So much so that I stopped using them when I was at work on Excel. I viewed the delay in testing from what was originally May to November/December as an opportunity to prepare myself for the testing environment because I had already been prepared with the material back in April. The syllabus material piece of the exam just became a maintenance process and my focus was to make the spreadsheet piece become habit so I didn’t have to consciously think about it during the actual exam time.
