For a while now I’ve had a hankering to do maths A level. Just for fun - I didn’t really like maths until I had a great teacher for GCSE and then it started to click into place.
That was a number of years ago so I’d definitely need a refresher before attempting A level. Now there are all sorts of apps and things available that I have no experience of - can anyone suggest the best way to revise the GCSE material before I attempt anything further?
