Course Topics
The topics listed below may appear in a variety of first-year high school chemistry courses including college-prep Chemistry and Honors Chemistry. These help pages are based on the idea that you should immerse yourself in topics through problems. Rather than textbook explanations or notes these topics pages focus on understanding concepts through the typical types of problems you might encounter.
