Where your marks live

Every question comes from one of six buckets — and they're not weighted evenly. This map should shape how you study.

A — Common occupational skills10%
B — Routine trade activities15%
C — Plans installation14%
D — Performs installation21%
E — Performs commissioning17%
F — Maintenance & service22%
Installation (D) + Service (F) ≈ 43% of the whole exam.

Almost half your marks are in what you do with your hands every day. Our course spends the most time exactly there.

What kind of questions?

~20–30%

Knowledge & recall — straight facts.

~50–60%

Application — a job-site scenario: here are the readings, what do you do?

~10–20%

Critical thinking — two answers look right; pick the best one.

Memorizing facts alone will not get you to 70%. You have to understand why — which is why every lesson ends in a worked scenario, not just a definition.

Your one-line strategy

Study to the weighting, not evenly

Spend your hours where the exam does — install and service first.

Understand why, not just what

Learn the mechanism so you can reason through scenario questions.

Never leave a blank

No penalty for a wrong answer vs. a blank — eliminate and make your best call.
