Before you pay
- Each term is 1 month (30 days from payment); it renews automatically and ₩45,000 (VAT included) is charged on each billing date.
- You can cancel yourself at any time under Account → Membership after signing in.
- Cancelling keeps your access until the period you already paid for ends.
- Time already used and credits already spent may fall outside the right of withdrawal (see the refund policy).
- Your 30 precision-scoring credits are issued fresh each billing cycle; unused credits do not roll over to the next month and expire when the cycle ends.
Credits are for Algo Precision AI scoring — 1 credit for a mock-test section (a full Speaking section or a Writing set), 0.5 for a writing or speaking practice set. Mock-test Algo Instant scoring and reading/listening practice are unlimited and free. Prices include VAT. You register a card once; it is then charged automatically each month. Remaining credits do not roll over to the next month.
