This year there is a new A level specification. This means that all of the old information on the site will no longer match nicely with the unit names of the old qualification. Fortunately the maths hasn’t changed too much, it’ll just be harder for me to categorise the information. It’s possible that I’ll get round to reorganising things but in the meantime I’m sure you’re clever enough to find your own way round is you need to, after all, you are doing an A level in maths (probably).
