I think the cover's the worst thing about it! Lulu puts severe limitations on cover creation, but I decided to use the same cover for the Kindle version, for the sake of... Hmmm, I'm not sure. I'm likely to change my mind about that in the next hour or two. But don't be put off by the cover. The content is far better, I assure you.
The "Grumpy Old Teacher" handle was my nom de plume for years when I was writing a blog about the uses of ICT in teaching. It sort of stuck.
Anyway, if you know anyone who's starting GCSE or similar exam courses this year, or taking the exams this year, then please get them to have a look on Kindle (£1.99) or Lulu (£4.99).
