What this subtopic covers
Wall reinforcement: size, lap splice length, clearances, alignment, cleanouts, and absence of loose rust, oil or millscale.
How to drill it
- Find the chapter of the International Building Code that carries this subject and read it once for structure, not retention: what lives here, what gets sent elsewhere, which tables exist.
- Write your own plain-language phrases for what this subtopic covers, then note the code's terms beside them. Mismatches between the two columns are exactly where exam questions cost you time.
- Run timed lookups: pick a requirement named in the descriptor above, start a stopwatch, find the governing text in your book, stop. Log the seconds. Past two minutes is a miss even when the answer is right.
- Weight your reps to the number above. Roughly 1 to 2 questions means this subtopic needs a handful of confident reps, not a week.
