Do the students have laptops/tablets, or do you use a computer room? I find spreadsheet activities a bit of a hassle because of the need to book a computer room (I do it for mortgages, but not much else)

Computer room - yes it’s a hassle. The only one available this year has 14 computers for a class of 18, which is why they have to work in pairs. Last year one of my lessons was timetabled in a computer room which was much easier.
