Last updated: November 9, 2026. Applies to purchases made on or after October 17, 2026.
Every course has a free demo, so you can try the questions, explanations and features before you buy. Full access is delivered immediately after payment.
Study guides in PDF (for example, Whole Body DXA and Body Composition). A PDF cannot be returned once it has been downloaded, so the 48-hour money-back guarantee does not apply to a study guide bought on its own. We refund it in full only for a technical problem that our support cannot fix within 14 days of purchase: the download link did not arrive or does not work, or the file does not open on your device. A refund ends the download link. When the guide is bought together with a course (a bundle), the 48-hour guarantee and the 14-day technical-problems rule apply to the whole bundle, as for the course alone.
Purchases made before October 17, 2026 keep the 14-day refund period that applied when they were made.
By completing checkout you agree to receive the digital content immediately. Where the law of your country gives you a right to withdraw from a purchase of digital content, you acknowledge that this right ends once access is delivered, except as described above. This policy does not limit any other rights you have under the law of your place of residence.
