Following the latest comments in the Telegraph today, do science teachers agree that OCR exams are harder? My current school switched from OCR Double and Single award GCSE to AQA 5 years ago when we had the specification revisions. At the same time we had jump in our result which has been sustained (though that may have been due to the change in content as well). Having seen 21st Century exams I have been struck by the lack of content and scientific knowledge required though I do think Gateway has a bit more challenge about it. My only experience of Edexcel was over 10 years ago and, at the time I thought it was much more challenging than AQA (or NEAB / SEG as was) particularly in its interpretation of the old POAE coursework. At A level I currently teach OCR biology and chemistry and I am very happy with these courses (and therefore unlikely to want to change from them) but I would be interested to hear other colleagues opinions on the differences in difficulty of the science A levels.
