Free Trial of the Real Classroom
The free trial is the real classroom, not a mock-up. Choose your trade and it opens in your browser with no account and no payment details, so you can see exactly how the course works before you decide.
One-time purchase, no subscription. Law & Business included.
What the free trial includes
- The first question from every category of your trade, with answer feedback and explanations.
- The first question from every Law & Business category, the exam most applicants take with their trade exam.
- The same screens as the full course: practice questions, missed-question review, flashcards and the Learning Hub.
- Nothing to install and nothing to enter: it runs in your phone, tablet or computer browser.
What the full course adds
The full course unlocks every question in your trade's bank and in Law & Business, saves your progress to your account, and includes the Settings controls that are hidden in the trial. It is a one-time purchase with no subscription and no renewal.

Do I need to create an account for the free trial?
No. The free trial opens straight from the link for your trade, with no account, no email address and no payment details.
Which trades have a free trial?
Every trade in the course has one. Each trial also includes a preview of Law & Business, so you see both parts of what you would study.
How is the free trial different from the demo videos?
