Types of Exam Questions

All Red Seal exam questions are written in multiple-choice format. A multiple-choice question consists of question followed by four possible responses (A, B, C, D). Every question has exactly one correct answer and three incorrect options. They are not misleading or trick questions, but the incorrect options are not always obvious.

There are three types of questions that you will see on Red Seal Exams:

Knowledge and Recall
Procedural and Application
Critical Thinking

Knowledge and Recall

This type of question tests your ability to recall and understand definitions, facts and principles.

For this trade, between 65 and 75% of questions that are this type.

Example of a Knowledge and Recall Question:

Which type of drawing supercedes the rebar placing drawing?

Electrical.
Structural.
Mechanical.
Architectural.

Answer: B

Procedural and Application

This type of question tests your ability to apply your knowledge of procedures to a situation.

For this trade, between 25 and 35% of questions are this type.

Example of a Procedural and Application Question:

How is a 6-m bundle of epoxy coated rebar rigged for lifting?

Nylon slings with a two-leg choker hitch.
Nylon slings with a two-leg bridle hitch.
Wire rope slings with a two-leg choker hitch.
Wire rope slings with a two-leg bridle hitch.

Answer: A

Critical Thinking

This type of question tests your ability to interpret data, solve problems and arrive at valid conclusions.

For this trade, less than 10% of questions are this type.

Example of a Critical Thinking Question:

If the building height is 62.5 m, and the under hook height is 84.37 m,how many 6-m tower sections weighing 1 750 kg (3 850 lb) each can be hoisted and placed inside an elevator shaft using a crane with a capacity of 5 tons?

Answer: B
