How do you set it out in a table? My group has students who also do further maths, alongside students who took GCSE a year ago and got a 5, so there's a big spread. Although in a lot of ways it's a great leveller, as much of the finance stuff is relevant and new to everyone.

It’s not a very nice table! I’ll try to find my exercise book tomorrow and take a picture. I try to base most of my teaching around this BossMaths applet which is really just a spreadsheet, so I get them to set out their work like that if I can. bossmaths.com/r16a/
