Free during beta

Every product is free while we're in beta. At launch the paid plan is $39 a month per student, and it covers every paid product — not a separate charge for each one.

Student plan · launch price
$39 USD per month, per student

Your child's side stays free with or without it — problems, hints, and every topic stay open. The plan is for you, the parent: where they stand and what comes next.

Each child has their own plan — their mastery map, weekly email and path are theirs alone. Two children means two plans; there is no sibling discount.

Available now · free during beta

  • Parent dashboard: your child's progress in one place, once their Depth and Competition devices are connected

Coming to the paid plan · in development

  • Mastery map across every skill — solid, shaky, and untouched
  • A weekly email: what they worked on, where they slowed down
  • Suggested next path, recalculated as they solve
  • AMC score trajectory: where the score is heading, re-measured every 6 weeks

Arithmetic is free and is not part of what you pay for.

Reserving is free and charges nothing. Nothing is billed during the beta, and we won't start charging an existing account without asking first.

Separate: the AMC Readiness report is $39 one-time — a single charge, not a subscription. See AMC Readiness →
