34 multiple-choice questions in College Board exam style. Each has four choices and a full explanation of why each option is right or wrong.
Read the question carefully before looking at the choices. Many APES questions have answers that look almost identical; small wording differences matter.
Know your curve shapes. J-curve = exponential, S-curve = logistic. Survivorship Type I/II/III each have a distinct shape: sketch them from memory.
Be ready for calculation questions. Rate of natural increase, doubling time, and TFR math show up often in Unit 3.
Read the explanations even when you got it right. Each one teaches a small fact that often returns in a different form on the exam.
