After-school Classes for Academic Success

Our after-school classes provide the perfect supplement to your child’s local school experience, whether they need extra help to catch up or are looking for enrichment.

Who are the classes for?

Mathematics, English, and Science are key to any future academic path, and further study in these areas will boost your child’s confidence and skills. In our classes, students are grouped by ability, not age, ensuring the right level of support or challenge. They’re taught by registered teachers in the afternoons/evenings, and recordings are available if your child misses a session.
