How to Read Tables and Drawings on Your Red Seal Exam
Many Red Seal questions do not ask you to remember a fact. They hand you something to read first: a table, a page from a catalog, a test record, a manufacturer's note or a numbered drawing. Then they ask what you would do. When our founder wrote the Red Seal Parts Technician exam in September 2026, a number of questions referred to tables and figures printed in a separate booklet, and the hardest part was not the trade knowledge. It was reading the exhibit quickly and correctly under time pressure.
This guide explains what the official exam information says about these questions, which trades receive a formula sheet at the exam sitting, and five reading habits that stop you from losing easy marks.
What the official exam information says
Every trade's exam information page on red-seal.ca splits the questions into three types: knowledge and recall, procedural and application, and critical thinking. Critical thinking questions are described as testing your ability to interpret data, solve problems and arrive at valid conclusions. Procedural questions often give you a situation and ask for the correct next step. Both types reward the candidate who reads the information in front of them carefully.
The official pages do not say, trade by trade, whether exhibits are printed in a separate booklet. If you want to know exactly what your sitting will look like, ask your provincial or territorial apprenticeship office. What the pages do state is the number of questions and whether a formula sheet is provided:

Five habits for exhibit questions
1. Read the last line of the question first. Know whether you are looking for a size, a time, a callout number or an action before you open the exhibit. Otherwise you read the whole table and still have to go back.
2. Read the title, the units and the notes under the table. The rule that decides the answer is often printed in a small note: "use the next larger standard size", "every spot must be within the range", "select the column for the voltage across the primary". Many wrong options come from skipping that note.
3. Find the right row and the right column before you read a number. The most common trap is a value from the neighbouring row or column: phase-to-ground instead of phase-to-phase, 20°C instead of 10°C, normal duty instead of heavy duty. The wrong options are usually real numbers from the same table.
4. For calculations, write the formula and the units, then check the rounding rule. Leaving out √3, forgetting to change feet to inches and rounding down when the rule says round up are the mistakes that produce the other three answers.
5. For numbered drawings, trace the path before you pick a number. Follow the flow of water, steam, current or load through the drawing. A callout that is one step upstream or downstream of the right part is a favourite wrong option.
How we built our exhibit practice
For each of the 20 trades, we read the trade's official exam information and occupational standard first, then wrote 12 questions that make you read tables, catalogs, test records and one numbered drawing from that trade's work: a building single-line diagram for Construction Electricians, a wall framing elevation for Carpenters, a steam pressure reducing station for Steamfitters, a spray gun for Painters and so on. Calculations use only the formulas on the official formula sheet, or, for trades without one, the formula printed in the exhibit. Every answer has a worked explanation.
The data in our exhibits is fictional, and we say so on every page. We do not reproduce code books or claim that these are real exam questions. They are practice in reading the kind of documents your trade works from.
Where to practise
Exhibit Booklet Practice and Practice by Block, where you pick any Major Work Activity on the official blueprint and drill it 18 questions at a time, are included in the 3-Month Pass, together with unlimited timed mock exams and the Free-Until-You-Pass Guarantee.
