Before You Begin
The PSI candidate bulletin lists 115 scored questions (plus 10 unscored), open book, 330 minutes, with a minimum passing score of 81. This mock matches that length and time and uses 81% as a practice target. It covers IBC 2021 building code topics only, not the NASCLA Contractors Guide business content.

- The timer starts when you begin and the exam submits itself when time runs out.
- Move freely with Previous, Next or the numbered navigator, and flag any question to come back to.
- No feedback is shown until you submit. Unanswered questions count as wrong.
- Nothing is sent anywhere; the exam runs entirely in your browser.
