A few updates (mostly to AQA notes). Some students have been asking for a practical revision guide. I will not be producing one at the moment. I took the decision to integrate the practical notes into the relevant chapters with the linked theory, and I think this is the best way to approach the practical material. The AQA paper 3 will be a combined practical and synoptic theory paper.
I have done some updates to practical material though, notably in 1.6 revision guide equilibria where I have included extensive notes on the practical measuring kc. This is not actually a required practical but it has been a favourite in the past on AQA practical papers. I have also included notes on solving equilibrium constant equations algebraically which I think are going to appear on the new exams (although not with quadratic equations).
I have changed terminology in 1.2 revision guide calculations to use uncertainty instead of error.
The other chapters I have changed have been labelled with (updated February 2017)
I have also produced a aqa-mechanisms-a-level-summary for the new syllabus
