AP Environmental Science — Populations

Populations is the third of 9 units in the College Board's current AP Environmental ScienceCourse & Exam Description. It builds on The Living World: Biodiversity and sets up Earth Systems and Resources.

Our Populations set has 12 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.
