You are in the right place.

The catalogue contains sample resource concepts, illustrative prices, and short PDF previews. The samples are clearly labeled. Private downloads and payments need connected services and a valid server-side product.

In a connected service, sign in to the same account and open My library. The server checks your access before creating a temporary download link.

Check Orders first. A return from PayPal is not proof of a completed payment. The server verifies the transaction before granting access. Do not create another payment while the outcome is uncertain.

Authorized file links expire. Sign in and request a new link from My library. If access has changed, the service will explain that a new authorization could not be issued. Downloaded files cannot be recalled from your device.

Your browser may open the PDF first. Use its share or download menu to save a copy. The wording and location differ between Safari, Chrome, and other mobile browsers.

This site checks whether its account service is configured. If it is not connected, the form explains this and does not create a pretend account. You can still browse the public preview.

Open Reset your password and enter your email. In a connected service, a recovery link is sent if the account exists. Use the link promptly and choose a unique password.

The writing studio tells you whether a result was saved to your account or only exists locally. A browser-only practice session is not automatically a cloud learning record.

Follow the notice on the feature you use. A lesson draft saved in your browser has not been sent to the studio. Use a private device for personal details. Read the Privacy notice for the intended data handling.

No. The studio first reviews your goals and preferred times. Only an explicit confirmation with a final start and end time means the lesson is confirmed.

The request form uses your device time zone and labels it above the time options. Check the device setting before submitting. The final confirmed time is shown in your account with its time zone.

No. Course pricing, teacher availability, and booking terms must be confirmed by the studio. A request does not create a course payment.

A little context helps: what you already know, where you want to use Chinese, and what feels difficult. You can be completely new. There is no need to prepare a perfect answer.
