Turn your results letter into a plan. Type the mark for each topic area, and this free tool ranks your weak blocks by how many questions they carry on the real exam, builds a 4, 6 or 8-week calendar, and shows the BC rules for your next attempt.

First, a word. Failing the Red Seal does not mean you are bad at your trade. The exam covers the whole trade across Canada, not just the work your shop does, and it is four hours of careful reading. Lots of good tradespeople need more than one try. What helps most is a plan aimed at the marks you actually lost.
Your privacy: this tool runs in your browser only. Nothing you type is saved, stored or sent to anyone. Close the page and it is gone.
Covers six trades for now: 309A Construction Electrician, 306A Plumber, 403A Carpenter, 456A Welder, 433A Industrial Mechanic (Millwright) and 421A Heavy Duty Equipment Technician. Have your Exam Results Letter open (it comes by email, and it is in the SkilledTradesBC Portal).
SkilledTradesBC says: “Your Exam Results Letter will have details of your mark on each topic area.” It also says the final mark is not an average of those topic marks, because each topic area can have a different number of questions. The final mark is simply correct answers divided by the number of questions, times 100. The pass mark is 70%, and results are rounded up, so 69.5% and up is a pass.
For Red Seal exams, the “topic areas” on the official breakdown are the trade’s Major Work Activities (often called blocks), lettered A, B, C and so on. We could not find a public sample of a BC results letter, so check that the headings on your letter match the block names in the tool. If they are worded a little differently, match them by meaning. If your letter shows something else entirely, call SkilledTradesBC Customer Service and ask what each line means.
The letter arrives by email within 30 business days of your exam, and you can see it in the Portal. (SkilledTradesBC currently says results take up to 30 days.) If you have questions about your result, contact Customer Service or an Apprenticeship Advisor within 30 days of getting it.
The tool does one simple thing that most people skip: it works out how many marks you lost in each block, not just which percent looks worst.
It is an estimate. Your letter and SkilledTradesBC have the final say on your marks.
Question counts are from each trade’s Red Seal Exam Information page. “Correct answers to pass” is our math using SkilledTradesBC’s 69.5% rounding rule. Code books are from SkilledTradesBC’s Active Certification Exams list (April 30, 2026); for certification exams, reference material is supplied and no outside material is allowed.
| Trade | Questions | Correct answers to pass | Blocks | Code book supplied in BC |
|---|---|---|---|---|
| 309A Construction Electrician | 100 | 70 | A–E (5) | Canadian Electrical Code 2024 |
| 306A Plumber (our breakdown) | 125 | 87 | A–G (7) | National Plumbing Code of Canada 2020 (provided) |
| 403A Carpenter | 100 | 70 | A–G (7) | National Building Code of Canada 2020, Part 9 |
| 456A Welder | 125 | 87 | A–D (4) | None listed |
| 433A Industrial Mechanic (Millwright) | 135 | 94 | A–F (6) | None listed |
| 421A Heavy Duty Equipment Technician | 135 | 94 | A–I (9) | None listed |
Every Red Seal exam has a four-hour time limit. Red Seal says new exams based on newer standards are under development for Construction Electrician and Industrial Mechanic (Millwright), and that some provinces are replacing the Welder standard. If you are in one of those trades, ask SkilledTradesBC which version you will write before you study.
From SkilledTradesBC’s Exam Rewrites page. Every rewrite needs a 30-day wait from your previous attempt.

Since December 1, 2023, Trade Qualifiers are limited to four writes of their certification exam. If you wrote the same exam before that date, SkilledTradesBC asks you to contact Customer Service to confirm your eligibility to rewrite.
Proof of upgrading uses SkilledTradesBC’s Proof of Upgrading form. The form lists three types: an upgrading or refresher course, a tutor, or your last level of technical training, with the instructor or tutor’s name, organization, phone number, end date and signature. SkilledTradesBC lists refresher courses at BCIT, KPU, Okanagan College, TRU and VCC on its Exam and Study Support page.
SkilledTradesBC scans each answer sheet twice and scores it by computer, and says changes to scores are extremely rare. A formal Request for Review of exam results is only possible on set grounds: an error in the facts or law, new evidence, or an unfair process. Talk to an Apprenticeship Advisor first. The form is due within 30 days of the written decision, the review can take up to 120 days, and you cannot reschedule the exam you are disputing until it is done. For most people, the faster path is a good plan and a rewrite.
Red Seal says its questions are not trick questions. Each one has four options and exactly one correct answer, but “the incorrect options are not always obvious.” In practice, people who know the work lose marks to reading, not to skill. The usual culprits:
Red Seal’s tips that work: try to answer before you look at the options, cross out options you know are wrong, estimate before you calculate, skip and come back to hard ones, and never leave a question blank. Each question is worth the same mark. Red Seal also says it is usually best to stick with your first answer unless you know you misread the question.
Nerves are normal, and they cost real marks when your mind goes blank. What helps:
A warning from Red Seal itself: “Claims of having real questions are false.” Using stolen exam material can cost you your apprentice status or your certification.
At least 30 days after your previous attempt. The 2nd attempt has no fee. From the 3rd attempt, certification rewrites cost $100 and need extra steps (an approved study plan with your Advisor for the 3rd, proof of upgrading for the 4th).
SkilledTradesBC scores the exam as correct answers divided by total questions, and the pass mark is 70% (69.5% rounds up). Your topic marks show where you lost marks; the final mark is not an average of them.
Match them by meaning to the closest Red Seal block. If you can’t tell, leave that box empty and the tool will fill it with your average. Customer Service can explain your letter.
No. It runs in your browser only. Nothing is stored or sent, and there is no sign-up.
Not to a Red Seal exam. SkilledTradesBC supplies the calculator, the code book when one is required, and the other materials.
SkilledTradesBC’s exam-day page lists materials for both paper-based and online exams. Your booking confirmation will tell you what to expect.
No. Red Seal says real questions are protected and change regularly, and that claims of having them are false.
