The right tutor changes everything.
Most kids have a moment when something clicks - a tutor whose voice they want to hear, whose pace matches theirs. When that happens, study has its own momentum. Your child opens the app, finishes more, and comes back to it without being asked.
Switch mid-session.
Your child can change tutors during a chat, and the new tutor picks up where the old one left off.
