Untimed training. Questions are mixed across categories. After two correct answers an item is retired; a miss resets it. Use this to learn the book, not to simulate exam day.A shorter timed sitting: 30 questions and 60 minutes. Good when you have less time. Same style as the long exam, half the length.This is the format that matches the live ICC B1 exam: 60 questions in 2 hours. Use it when you can sit for the full stretch so you practice pacing and endurance, not just content.Your scores, how many sittings you have taken, and which categories are strongest or weakest.

This is a computer-based training system, not only a mock test. Practice, timed exams, progress, and end-of-sitting review all live here. ICC does not sell one “R5 exam.” R5 Residential Combination Inspector is awarded after you pass four separate 60-question / 2-hour tests.

R5 = B1 + E1 + M1 + P1. A bundle code unlocks every module we have published. A single-module code unlocks only that exam.
R3 Residential Plans Examiner is a different credential (office plan review). Same 2021 IRC, not part of R5. Sold as its own module.
Pass score on the live tests is a scaled 75. Open book. Only the listed book for that exam.
Which mode should I use?
Hover any start button for a short reminder. Here is the full picture.
Practice is how you learn. There is no clock. Each set still uses the same B1 topic mix as the live exam (more walls and public safety, fewer administration items). Get an item right twice and we stop asking it; miss it and it comes back. On each question you can open IRC location or Hint if you are stuck. Try without them first — the live exam will not offer those buttons.
30-question exam (60 minutes) is a shorter timed mock. Use it when you cannot sit for two hours.
60-question exam (120 minutes) matches the live ICC B1 exam: 60 questions, 2 hours, and the same content-area balance. When you have a clear morning or afternoon, take this one so you practice pacing and endurance the way the real test will feel.
These sittings are still a study tool: after you answer, you may reveal the IRC location and a worked explanation. The live exam will not do that.
