The Red Seal Carpenter exam is 100 questions, and the Red Seal Program publishes exactly how they're distributed. Most practice material ignores that. Ours is weighted to match it, section by section.
A pattern shows up again and again from people who've written this exam: scoring in the high 80s and 90s on practice tests, then walking out of the real thing with a 67 or a 69. The pass mark is 70.
There's a structural reason. The Red Seal Program publishes the mix of question types on the Carpenter exam — and only 5–15% of it is straight recall. Between 75% and 85% is procedural: apply what you know to a situation on site. Most question banks sell you recall, because recall is cheap to write.
Our rule: every question maps to a named sub-task in the public Red Seal Occupational Standard, and the set as a whole matches the published type mix. If a practice score doesn't predict a real score, it isn't practice — it's reassurance.
Answer them honestly, then open the explanation. Note that every wrong option gets a reason too — that's where the learning is.
When laying out a common rafter, what adjustment is made at the ridge plumb cut?
The theoretical rafter length runs to the centreline of the ridge. Since a rafter bears on the face of the ridge board rather than its centreline, each rafter is shortened by half the ridge thickness. The two opposing rafters together account for the full thickness.
A slab is placed on a hot, windy day. What is done to prevent plastic shrinkage cracking?
Plastic shrinkage cracking occurs when surface water evaporates faster than bleed water rises. Fogging or an evaporation retarder slows surface evaporation until the concrete has set enough to resist cracking.
A wall 3.6 m (12 ft.) long is laid out with studs at 400 mm (16 in.) o.c., with a stud at each end. Not counting additional studs at openings or corners, how many studs are required?
3600 mm ÷ 400 mm = 9 spaces. A layout with a stud at each end has one more stud than it has spaces, so 9 + 1 = 10 studs.
How are horizontal courses of sheathing membrane lapped on a wall?
Sheathing membrane sheds water by shingle action. Lapping the upper course over the lower one means any water running down the face of the membrane stays on the outside of the course below.
In a load-bearing wall, what carries the bearing load at each end of a header?
The jack (trimmer) stud runs from the header down to the bottom plate and carries the header's bearing load into the wall below.
