What it is
ChemPath is a complete path from zero to AP Chemistry in five stages: Chemistry Foundations, High School Chemistry, AP Chemistry, Exam Prep and College Organic Chemistry. Every lesson has interactive demos, step-by-step examples and a short quiz, every chapter has practice questions, and the AP part adds exam drills, a mistake log and full-length practice exams.
Everything is free and bilingual; switch between Chinese and English at the top right of any page.
Who it’s for
Students starting chemistry from scratch, students taking high school (Honors-level) chemistry, and students preparing for the AP Chemistry exam. If you’re not sure where to start, take the placement test on the home page. Teachers are welcome to use it in class.
Where the content comes from
The lessons and practice questions are written for this site. The AP part follows the units and topics of College Board’s current Course and Exam Description (CED), and explains the exam format, scoring and equation sheet as they are on the current exam.
Privacy
ChemPath has no accounts. Your progress, practice scores and mistake log are saved only in your own browser, and they disappear if you switch browsers or clear the site’s data.
To see how many people use the site and which pages they read most, ChemPath counts visits anonymously with Vercel Web Analytics. It uses no cookies, doesn’t record IP addresses, and doesn’t link visits to any person; it only totals page views, the site a visitor came from, their country or region, and their browser and device type.
When you send feedback, we receive only what you write, the page you were on, and any contact details you choose to leave.
Found a mistake or have an idea?
Every page has a “Feedback / Report a problem” button at the bottom, and each question has a “Report” button. Reports are read and fixed as soon as possible.
