Watch Passmate decide how to teach.
Answer as a child would. Left: what they see. Right: what it learns about them.
A small, close-knit Catholic prep for girls with an excellent ISI verdict and the personal attention that comes with just over 200 pupils.
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.
