Watch Passmate decide how to teach.
Answer as a child would. Left: what they see. Right: what it learns about them.
A distinctive online option for families wanting structured independent education without a physical campus, with both British and international qualification pathways under one virtual roof.
That’s where Passmate comes in. Tutoring is the most effective thing in a child’s preparation - a well-tutored child can outperform the vast majority of their peers. Passmate works alongside your tutor, not instead of them: it learns how your child thinks, finds the gaps, and shows the tutor exactly where to spend each session - so the limited time you have lands on what actually decides a place.
Works alongside your child’s tutor - not instead of them.
