AP Biology — Chemistry of Life

Chemistry of Life is the first of 8 units in the College Board's current AP BiologyCourse & Exam Description. It opens the course and sets up Cell Structure and Function.

Our Chemistry of Life set has 8 practice questions, each with a written explanation, a one-line key takeaway, and a rationale for every wrong choice — so you learn why the right answer is right and why each distractor is tempting. You can work them as a timed set or read the worked solutions straight through.
