Edexcel Past Papers App
This app is good because it has many features including all past papers from up to 5 years ago including the mark scheme so you can correct your answers. However a problem with this is that the mark scheme has to be printed in order for you to write or edit it. I would recommend this app because it is free and you can study other languages other than French. The only thing I would like improved about this app is to be able to type on the papers without having to print them off.
