How the drills work
- There are 6 drills, always in the same order.
- Press start to show a drill and begin its clock. Press check to stop it.
- After each check you see the answer, a short explanation and a find-it-fast tip for that lookup.
- At the end you see the seconds for each drill and the average.
Your time depends on how your book is tabbed and which edition you use, so compare it only with your own earlier runs. The IRC tabs guide lists tab locations for the 2021 and 2024 editions.
These are original practice drills, not exam questions. They do not reproduce code text.
