Observations that were made, in no particular order:
One teacher said that they found the questions looked much more familiar for the board they currently used (AQA) than on other boards. Teachers of other boards did not express this view. It was though felt that Discrete Mathematics was likely to be more familiar, both in content and style, with your current board. This is a significant but not game-changing observation!
There was concern about the additional compulsory pure content for AQA, which gives much reduced flexibility. Some years you wouldn't want to do this with your cohort. It's a 2 hour paper too. This might be game-changing!
There seemed to be very little problem solving involved in the OCR (A) and AQA papers.
One teacher observed that the compulsory pure paper for one board was very 'differential equations heavy', but it was noted that DE is a very significant topic, so this is likely to be true on all papers.
Teachers looking at the Edexcel papers said that the statistics looked very similar to what is in current Edexcel S2 and S3 modules.
Personally, I remain convinced that the best specifications are the ones which offer plenty of choice, and that you should consider which topics you want to teach/want your students to learn. These things will have a bigger impact long term than superficial similarity with current specifications and papers.
If you foresee the need for CPD on any Further Mathematics content, do let me know as soon as possible. We will do what we can!
