This page assembles the whole site — five lessons, eight homework problems, four assessments and the complete unit test — into a single document with every solution expanded and every diagram included. It is what the submitted PDF is made from.

Wait for it to finish building, then print. In Chrome and Firefox choose Destination → Save as PDF, keep the default A4 size, and leave “Print backgrounds” on so the shaded planes in the diagrams come through.

The mathematics is drawn as vector paths, so it stays sharp at any zoom and does not depend on any font being available to the printer.
