About

There will be a syllabus tailored to the course and exam description for AP Chemistry that I will review for the first session. Each session will be around an hour, and recommended* practice materials will be around 5 multiple choice questions and 1 free response question each time.

✋ ATTENDANCE POLICY

While optional, please try to be here everyday. Since we're going at such a fast pace, it will be difficult to teach absent students previous material.

If you miss a session, just contact me and I'll provide the materials I'll have used during that time period.
