Paying yearly saves $59.88 — 50% off the monthly rate.
One payment up front covers the whole year and everything added to the bank during it. If you'd rather keep it open-ended, the monthly plan is $9.99 and you can stop any time.
Questions
- What do I get without paying?
- Fifteen questions with no account at all, and 60 — ten in every one of the six subjects — once you create a free account. Every one of them comes with the full rationale.
- What needs a subscription?
- The rest of the question bank, timed exam mode, flashcards built from the questions you miss, and a week-by-week study plan to your test date.
- Can I cancel the monthly plan?
- Yes, whenever you like. It's charged month to month, and cancelling stops the next charge — you keep access to the end of the month you've already paid for.
- How does the annual plan work?
- It's one payment up front that covers all 12 months, not a subscription that bills you each month. Because the whole year is paid in a single purchase, it can't be cancelled part-way through.
- Does the bank keep growing?
- Yes — new questions are being written, and a subscription includes every one added while it's active.
