We produced these apps for the outgoing A Level specification and the 2012 GCSE specification. They are both for personal use by students on their iPhones/iPads.
We hope to produce new apps for the current specifications. One of the problems in doing this is that whereas we get feedback on our other products in emails and on the phone, the only feedback on our apps came from a tiny number of reviews. If you or your students used these apps, we would really welcome feedback on them. If you didn't, we would still be interested in your views on what you would like to see in future Churchill Maths apps. Get in touch here.
