Every plan shows how much tutoring is left this week and when it resets. Reading a worksheet or building a quiz counts as several replies. When it runs out, you get a study plan from your own cards and topics until it resets.

Exam Pass ($6.99): About 300 extra replies for 7 days. One payment, does not renew. Works with any plan.

If you stop paying, your courses stay readable and nothing is deleted.
