What we believe
- Practice for everyone
- Your school shouldn't decide how much you can practise.
- The syllabus is the spec
- If you didn't choose it, it isn't on the paper.
- Correct before fast
- Every question verified, even when it takes longer.
- Teachers stay in charge
- Read every question. Replace any you'd change.
