  • Each option renews at its selected 1-, 3-, 6-, or 12-month cadence until canceled.
  • Stripe shows the amount due before you confirm payment.
  • Keiko Study does not guarantee a score and is not affiliated with an exam owner.
  • New features can be added later, but this page lists only the current offer.
