Certification
The course is free and always will be. The exam is the other thing: one timed sitting, covering the whole syllabus, that produces a result you can put in front of an employer.

How the exam works
One timed sitting
The clock starts when you do and runs on our server, so closing the tab does not stop it. Your answers save as you go, and you can pick up where you left off if something goes wrong.
No two papers alike
Questions are drawn fresh from a bank several times the size of the paper, weighted to the syllabus. Options are shuffled per candidate, so an answer key is worthless.
A certificate worth showing
Pass and you get a certificate with a public link anyone can check, plus a breakdown of how you did by topic — useful whether you passed or not.
One payment buys one sitting. Failing does not entitle you to another, and we do not refund a sitting you chose not to use — but if our systems are why you could not sit or finish, you get the attempt back. The refund policy says exactly what that covers.
