Directions. Each question has four answer choices — select the single best answer. Difficulty rises gradually from Question 1 to Question 100, and topics are interleaved on purpose so related ideas reinforce each other, the way they may appear together on your actual exam. Try each question before opening its Hint. After you answer, a short explanation appears immediately below the question. When you're ready for a paper copy, select Save as PDF — the printed version leaves the choices blank for you to bubble in by hand, with a complete answer key on the final page.
