Do the 10 free questions change?

Yes. The selection changes every day at midnight UTC within a limited free pool. You get the same selection throughout the day; questions reappear over time. This does not mean 10 brand-new questions are added every day.

Are public question pages and the free quiz the same thing?

Public question pages are available to read without an account, including their explanations. The free quiz lets you answer a selection of 10 questions. Full access adds practice across the active Basic bank, full mock exams and targeted revision.

Does CertifBus award KNX certification?
