Where are the nails placed on a standard three-tab asphalt strip shingle, and how many are used in a normal-wind area?
- Four nails, in the headlap above the sealant strip, driven flush
- Six nails, below the sealant strip, heads set just under the surface
- Four nails per strip through the tabs, so they are sealed by the next course
- Four nails, below the sealant strip and above the cutouts, driven flush
Show the answer
D. Correct. The nail line is about 140 to 150 mm (5-1/2 to 6 in.) above the butt: below the sealant strip and about 16 mm (5/8 in.) above the top of the cutouts (the NBC minimum is 12 mm), one nail 25 to 40 mm in from each end and one above each cutout. Each nail then also holds the top of the course below. Nails are driven flush, not overdriven, and must penetrate the sheathing or go through it; six nails are used in high-wind areas.

An unused brick chimney that passes through the main floor, second floor and roof of a house is to be completely removed. What is the correct procedure?
- Cut it off just below the roof, roof over the hole and leave the rest
- Top down in large sections cut free with a masonry saw, lowered by rope
- Top down brick by brick, chuting debris, headering each opening as you pass
- Top down brick by brick, stacking the brick in the attic to lower out later
Show the answer
C. Correct. A chimney is freestanding and is taken down in the reverse of how it was built: from the cap downward, a course at a time, with the masonry chuted or bucketed out rather than dropped. As the work passes each level, the framing that was trimmed around the chimney is headered off with doubled members in hangers, and the roof hole is sheathed and roofed. Shore any floor framing that was resting on the chimney before the brick that supported it is removed.

A wall-mounted handrail on a stair must be graspable for its full length. What minimum clearance does the NBC require between the handrail and the wall?
- 25 mm (1 in.)
- 50 mm (2 in.)
- 75 mm (3 in.)
- 100 mm (4 in.)
Show the answer
B. Correct. NBC Part 9 requires at least 50 mm clearance between a handrail and the wall or any other surface behind it so the rail can be gripped along its length. Standard handrail brackets provide this when the rail is mounted on them; check if a thick profile or a tiled wall reduces it.

A 356 mm (14 in.) I-joist frames into an LVL header. The carpenter has a face-mount hanger sized for a 241 mm (9 1/2 in.) joist. How should the joist be hung?
- Use a hanger listed for the 356 mm joist depth, per the manufacturer
- Use the hanger as is and add an extra nail through the flange into the header
- Toe-nail the joist to the header with four 82 mm (3 1/4 in.) nails instead
- Notch the bottom of the joist so it sits in the smaller hanger
Show the answer
A. Correct. A hanger made for a 241 mm joist leaves the top of a 356 mm joist unsupported. Manufacturers require web stiffeners where the hanger sides do not reach and laterally support the top flange, and a hanger shorter than about 60 % of the joist depth also needs added restraint against joist rotation. Use the hanger the manufacturer lists for this joist and load, and fill every hanger hole with the specified nails.

Timber shoring is being installed in a 2.4 m (8 ft) deep excavation: vertical sheathing, horizontal walers and cross-trench struts. In what order should the members be installed as the crew works down from the top?
- Struts first, then walers, then sheathing
- Walers, then sheathing, then struts, working from the bottom up
- Sheathing, then walers, then struts, working from the top down
- Sheathing and struts together, adding walers only where the soil looks loose
Show the answer
C. Correct. Sheathing is placed tight to the excavation wall, walers are set against the sheathing, and struts or screw jacks are tightened between opposing walers. Installation proceeds from the top down so the upper soil is supported before workers go deeper; removal is the reverse, bottom up.

The 403A exam at a glance

Question mix — weighted to the blueprint
The 403A is one of the most procedure-heavy Red Seal exams — the questions ask you to carry out a task the right way and in the right order. Recall-only question banks don't match the question mix the published exam breakdown sets.

Where our numbers come from
Built to the published standard.
The question counts above are the Red Seal Program's own exam breakdown for Carpenter, and every question in our 550-question bank is mapped to a sub-task of the Red Seal Occupational Standard — 22 tasks and 81 sub-tasks, each one covered. When the standard is revised, we re-check the map and the weightings against it. For what each block covers and where to spend your study time, read the 403A exam guide.

Why practice scores mislead
You can ace recall and still fail the 403A.
Most question banks drill what you can recall, because recall questions are cheap to write. The 403A is overwhelmingly procedural — it asks you to carry out a task the right way, in the right order, to code. That gap is why people walk in confident and walk out surprised. TicketPrep weights every test to the published blueprint, so a weak section here is a weak section there.
