My history teacher said that there isn't a gap between AS and A2. Just going through the course today it seems to be much of the same, just a bigger time period. So there will be more to learn, but it seems that the content wont be anymore difficult to learn. But in English lit she was saying it'll be a step up regarding the level of writing in our text analysis in exams etc, and the exams are closed text exams so that will make it harder. Business doesn't appear to be any harder yet either...
