Frequently asked questions
Can I try before I buy?
Yes. Each course opens with a free demo section so you can try the questions, explanations and progress tracking first. No account is needed.
How much does full access cost?
Each course is a one-time payment of $35. There is no subscription.
Are these the real exam questions?
No. All questions are original practice material written to match the topics and weighting that certifying bodies publish. They are not actual examination items, and practice scores do not predict official scores.
Can I get a refund?
Yes. Within 48 hours of purchase for any reason, and within 14 days if the course does not work on your device and our support cannot fix it. Try the free demo first to make sure it fits you. See the Refund Policy.

Help with access
How do I get access after paying?
After checkout you return to the course already unlocked and see your license key (CTTP-… for CT, DEXA-… for BoneDensity Prep). The key is also emailed to you from support@digitaltrainingprep.com. Copy it and keep it: it is your proof of purchase and lets you reactivate the course at any time.
I paid, but the course is still locked. What should I do?
This usually happens when the course is opened in a different browser or on a different device from the one used at checkout, or inside an app such as Instagram, Facebook or a mail app. Open digitaltrainingprep.com/dexa/ or digitaltrainingprep.com/ct/ in Safari, Chrome or Edge, choose Unlock → Enter license key, and paste the key from your email. If you see “already active on another device”, email us and we will reset it within 24 hours.
Where is my license key?
It is shown on screen right after payment and emailed to the address you used at checkout, from support@digitaltrainingprep.com, with the subject “Your … license key”. Check your Spam or Promotions folder. Still nothing? Email us with the address you paid with and we will resend it.
Can I use the course on more than one device?
The license is active on one device at a time. To switch, enter the same key on the new device and choose Move license to this device (or first choose Unlock → Deactivate on this device on the old one). Your progress is stored in each browser, so it does not move with the key.
I got a new phone or computer, or cleared my browser.
Just enter your key again in the course. If it says the license is active on another device, choose Move license to this device: this device unlocks and the old one loses access. You can move the license yourself up to 3 times in 30 days; after that, email us and we will move it within 24 hours. Tip: when you clear your browser history, leave Cookies and site data unchecked so the course stays activated and keeps your progress.
Can I share my key with a friend?
No. Each license is for one person. Your friend can try the free demo and buy their own access; the key only works on one device at a time.
How do I contact support?
Email digitaltraningcourses@gmail.com, or simply reply to the email with your license key. Please include the email address you paid with, your device and browser (for example, iPhone + Safari), and a screenshot of any message you see. We reply within 24 hours.
