Hi, Last year we trialed iGCSE rather than GCSE (mainly due to being able to use a calculator and there only being two papers). We took the January paper and results were great, beating the previous summer series, and so I am very keen to make this our main entry. Whilst the vast majority of content is transferable, I am really interested in exploring if there is a favourite textbook or similar that teachers refer to. I am not looking for a class set of student textbooks as I want teachers to have the freedom to teach in their own way, but I do think it would be helpful to have a standard reference point that all teachers could refer to. Any recommendations/ advice greatly appreciated!!
