Every question is written from the public exam guide and public documentation. Every correct answer cites a specific source.
We never use content from real exams or from non-public training materials. Requests for “exam questions” are refused.
How we check questions
Each draft goes through a separate review that opens the sources and checks every quote. A person reads every question before it enters the bank.
Every question has a version number and date. When the exam guide changes, we review the bank.
How we calculate your score
The exam guide splits the exam into 7 domains; on this site we call them topics. The free check starts with 5 questions, one from each of the 5 topics with the largest weight in the exam guide. You see how many you answered correctly and a likely range for that share: the 95% uncertainty range (Wilson interval). With 5 questions the range is very wide: it is a first look, and we show it that way.
After the result you can answer 10 more questions across all 7 topics. Your first answers are kept and the result is recalculated on all 15. More answers give the estimate more evidence; the range may shift and does not always get narrower.
We rate a topic only from 10 questions. In the free check each topic has one to three questions, so we show correct answers out of the questions asked (dots) and no percentage or ranking; the topic panel says “Not rated yet”. Topics with no questions in your check sit in the clouds and are marked “Not tested yet”.
Topics to review lists topics where you missed questions first (up to 3, with any others under “Also missed”), then topics not tested yet. It is a place to start, not a diagnosis. Plans with AI debriefs add a study plan after each session.
If you rate how sure you are after each answer, the result also counts questions where you felt sure but were wrong.
What “ready” means
A 5- or 15-question check is a first look, not a final grade, so it never tells you whether to book the exam.
Readiness criteria for longer practice exams are not defined yet. They will not be the official pass mark.
How the AI debrief works
The debrief only uses the approved explanation of the question and its sources. It asks about your reasoning first, then explains.
AI can be wrong, so sources are always shown. You can report any debrief as incorrect.
