No account or payment card needed: a 10-question session with explained answers. In timed mode, this session lasts 9 minutes.
The free selection rotates each UTC day; sessions may share questions. This short format lets you try the practice experience, but is not a full mock exam or a prediction of passing.

“I was a bit worried I’d end up on a complicated platform, but it’s the opposite: you arrive, you answer, and the correction appears straight away with the explanation. No manual needed. In Learn mode I understood my mistakes as I went, and a few days before the exam I did back-to-back timed mocks: 100 statements in 90 minutes, the real format with the real scoring (+1 / −0.5 / 0). On the day of the theory exam, it felt like doing another session at home. Zero stress, certified on the first attempt.”
Julien R., electrician retraining
“My KNX Basic course cost me over €1,000. For €19, I got 3 months of access to the whole question bank, the full mock exams and the progress tracking. I switched the interface to German to revise in my own language, corrections included — everything is the same. At that price I expected something basic… it’s the opposite. And it’s a one-time payment, not a subscription that quietly renews. Clearly the best investment of my preparation.”
Torben L., electrical installer (Munich)
“What blew me away was the tracking. After each session, my dashboard shows my results by skill: I immediately saw that topology was solid, but that I was stuck on ETS downloads and group addresses. I ran targeted revisions on just those topics, then a mock exam to check. In two weeks I went from 68% to 92% correct answers. Instead of revising blindly, you know exactly where you’re losing points.”
