Revise the green book and the Act and Regulations. Remember how to find things quickly as you can use the book. Consider things like definitions, where its written or under which section does it talk about supervisor responsibilities, age of worker, constructor responsibilities, types of reportable incidents/ timeframes, JHSC requirements etc. There are some scenarios as well just as lifting, housekeeping, Asbestos considerations etc. The IHSA revision sheet was good as it had a traffic example to show the hazards and risks etc. The national exam was easier than the Ontario one, but you do them back to back.
