FMCBE - working with excel

Hi All, This is for anyone sitting the CBE this Friday. i've been practicing some OT questions on ACCA just to get used to the format and also used to how the excel function works in this exam. I use excel every day in work but I'm actually finding excel in the CBE specimen exams quite tedious to use. Constantly having to format cells with figures to include commas (really just to make it look neater but also to keep track of the large figures being used in a computation). As some of the workings are both text AND figures..I can't just highlight all of the cells and format them the same which would have been very handy. Also would have been useful for them to just include the , at the top in the formula bar which is usually the case in excel. Anyone else finding this very frustrating? i'm panicking now that this is going to use up valuable time.
