How the drill works
- Set a target pace of 60, 90 or 120 seconds a question. It is only your own goal.
- There are 5 questions, always in the same order.
- Press start to show a question and begin its clock. Press check to stop it.
- After each check you see the answer, a short explanation and your time against your target.
- At the end you see your score and the time for each question.
Your time depends on how your book is tabbed and which edition you use, so compare it only with your own earlier runs and your own target. The questions follow the section numbering of the 2024 edition of the IRC, which differs from the 2021 edition in Chapter 3, so check your book's edition.
These are original practice questions, not exam questions. They do not reproduce code text.
Lookup drill FAQ
How does the ICC B1 lookup drill work?
Pick a target pace of 60, 90 or 120 seconds, then work five questions in a fixed order. Each one describes a field situation. Find the section or table in your own 2024 IRC, type or pick its number and press check to stop the clock. You see the answer, a short explanation and your time against your target.
Which IRC edition do I need?
The questions follow the 2024 IRC, whose Chapter 3 numbering differs from the 2021 edition. The B1 is offered on both, so drill with the edition on your exam booking. ICC offers free read-only access to the 2024 IRC online, or use your own copy.
How does the drill help on the open-book B1?
The B1 gives you 60 questions in two hours, about two minutes each. A lookup that keeps taking more than a minute leaves too little time to read the conditions, so give that topic a tab or learn its index term, then run the drill again.
How fast should I be?
There is no set time to hit. Your time depends on how your book is tabbed and which edition you use, so set your own target and compare each run only with your earlier runs. When a question beats your target twice in a row, lower it.
