What the chart doesn't show
How much is live. Minerva's and Highgrove mix live lessons with work on your own, so they cost less but ask more of your child. A school with classes of 6 to 10 will feel very different from one where some lessons are lectures to 50.
Exams. Only a few schools run their own exam centre, and none includes the entry fees. Sitting exams as a private candidate explains what that costs.
