This is an AP Chemistry practice test course. This course contains six tests with carefully selected high-quality multiple-choice questions to test basic knowledge, essential understanding, and enduring knowledge of concepts in the eight topics of Unit 2: Molecular and Ionic Compound Structure and Properties. This course can help you prep for a unit test or the AP chem exam.
Questions in each test are nicely organized from easy to medium to hard to AP exam-type questions. You’ll see this throughout my practice test courses. I do this to help you build confidence in the beginning, and strengthened your
My AP Chemistry Practice Tests follow the 2020 AP Chemistry Framework.
