Praxis Chemistry: Biochemistry Objectives

Individuals hoping to become licensed teachers in most states are required to take at least one test in the Praxis series as part of the process. Those taking the Praxis Chemistry: Content Knowledge test have usually finished at least a bachelor's degree program, including studies in chemistry and education. The Praxis Chemistry: Content Knowledge test measures your mastery of concepts taught in secondary school chemistry. Biochemistry question are categorized under the Periodicity and Reactivity; Chemical Reactions, Biochemistry and Organic Chemistry section of the test, which encompasses 23% of the test's 100 total questions.

The actual Praxis Chemistry: Content Knowledge exam has paper and computer-based formats. Practice the exam's multiple-choice question style by taking the self-assessment quizzes after each video lesson.
