How the improvements happen
No secret curriculum. The mechanism is on this site in plain view: method-mark working trained weekly, error patterns logged and repaired, Paper 1 fluency drilled, and a timed past-paper engine in exam season. Done 1-to-1, every week, by a specialist. The grades follow the process.
A note on honesty
We do not guarantee grades. Nobody honest does. We guarantee the process above, and we put the first hour where our mouth is: the free trial means no family ever pays before seeing the teaching work on their own child. That is the only grade guarantee worth anything.
