check if your province’s curriculum changed recently (e.g., Ontario de-streaming). Many used copies of the print version are $5–10 – the PDF’s convenience may not be worth the screen fatigue.

This is a specific request for a of Complete MathSmart 9 (presumably the PDF edition). Since I cannot access or download proprietary PDF files, this review is based on: (1) the established structure of the Complete MathSmart series for Grades 9–12, (2) curriculum alignment with Canadian provinces (Ontario, BC, Alberta), and (3) common feedback from educators, parents, and students who have used the PDF version.
