2. Where to Focus Your Study Time
MWA D (Framing) at 20% is the single biggest block — floor systems, wall framing, roof systems (rafters, trusses, engineered lumber) show up the most. But unlike more top-heavy trades, Carpenter spreads real weight across concrete (16%), exterior finishing (14%) and interior finishing (14%) too, so don't skip any section entirely.
- Framing calculations: rafter length/pitch math, stair stringer layout, joist span tables.
- Concrete work (16%): formwork pressure/bracing, rebar placement and cover requirements, finishing sequence and curing.
- Renovations (10%): smaller weighting but frequently missed — know load-bearing wall identification and temporary shoring basics.
Practice Question: When laying out a gable roof, what term describes the horizontal distance from the outside wall to the center of the ridge?
A) Rise
B) Span
C) Run
D) Pitch
Correct Answer: C) Run (Run is the horizontal distance used with rise to calculate pitch and rafter length)
