Where they can create their account and register children (create a card: age, English level, schedule, etc., etc.). The children will need to link a group, a history of attendance and success (Excel), a wallet for bonuses and additional. useful functions. The ability to pay with bonuses for goods or services on the same site. We are waiting for your suggestions
