Questions

Before you ask

Is this the actual Red Seal exam?

No — exam questions are secure and can't be published. These are original practice questions written to the Red Seal Occupational Standard for Sheet Metal Worker, covering the same topic areas, weightings, and style of trade math you'll face.

What do I need to pass the real exam?

The interprovincial Red Seal exam for Sheet Metal Worker is a multiple-choice exam (125 questions) and the pass mark is 70%. Your province or territory sets the sitting and the fee.

How do I pass the sheet metal Red Seal exam?

Prep the way you'll be tested: timed mock exams scored against the 70% pass mark, practice sets weighted to the Red Seal Occupational Standard, and a read of the explanation for every wrong answer until the reasoning sticks. The topic breakdown after each run shows exactly which blocks — layout, fabrication, air handling math — need more work before you sit the real exam.

Imperial or metric?

Both. The exam draws on both systems, so the bank does too — duct sizes in inches, thicknesses in gauge and millimetres, and conversions where the trade actually uses them.

I'm a 3rd-year apprentice. Is it too early?

No. The topic breakdown shows you which blocks your schooling hasn't covered yet, and the explanations fill gaps. Most people start serious prep about six months out from writing.

Does it cover the other HVAC trades?

This bank is Sheet Metal Worker only. Refrigeration and Air Conditioning Mechanic is a separate Red Seal trade with its own standard.

When do I get access to the full question bank?

Right away. Both plans give you real-time access to the full question bank for your final Red Seal exam — the complete library for your trade, not a sample set — from the moment you sign up, and every question added later is included.
