🔥 Coach’s Tip
Don’t just study questions — study the tasks. The Red Seal exam is task-weighted.
If a trade’s RSOS shows 35% of the job is electrical troubleshooting… you bet 35% of your exam is too.
“If you train the task, the test will feel familiar. If you only train the test, the job will crush you.”
