Scope: public documentation. Saved learner information requires account access.

## Keep practicing for free

Daily practice, guided cases, short timed practice, and explanations are part of the free experience. You can keep attempting practice without purchasing a subscription. Some mission themes unlock with earned Gems.

## What Plus adds

Plus adds 45-, 90-, and 180-question practice exams and extra Progress charts. You need an active Plus membership to use them. Your basic charts and saved results stay free.

Locked charts are previews. Any example values shown there are illustrative, not hidden results about you.

## How does Plus billing work?

Tirtle Plus is offered at $9.99 per month when purchasing is available in your study space. Opening the Plus offer doesn’t start a subscription or charge you. Checkout happens on Stripe after you choose Join Tirtle Plus.

For purchases sold through Link, Link handles the payment receipt and payment support. To review or cancel, open Membership and choose Manage billing. You can also use your Link account. If the Plus button says memberships are coming soon, online billing is not active yet.
