S. S.

Solid curriculum covering all the expected topics. I would have liked occasional built-in review sessions, but overall we're happy with the progress.

Impressed with how the course develops scientific reasoning and problem-solving. My child frequently talked about the virtual labs and modeling activities.

Very informative and well-organized; my only minor gripe is that a few units moved quickly and could use extra worked examples.

Good topics and useful simulations, but five lessons a week for 18 weeks proved to be a heavy time commitment for our family schedule.
