Review Mid-term Some advice for using this practice test to study for the mid-term 1.​ The test is organized like the text. The following index lines up the questions with the corresponding chapters: a.​ Chapter 1 Questions 1 to 10 b.​ Chapter 2 Questions 11 to 15 c.​ Chapter 3 We did not do this chapter d.​ Chapter 4 Questions 16 to 37 (Markets, Demand, Supply) e.​ Chapter 4 Questions 38 to 55 (Equilibrium Prices and Quantities) f.​ Chapter 5 Questions 56 to 83 g.​ Chapter 6 Questions 84 to 94 (Just the first half of chapter 6 113 to 124) Within the chapter questions, they are ordered by location in the chapter. For example, if you get question 83 wrong, then you know that the relevant material in chapter 5 will be at the end of the chapter. If you miss question 60, you know the material is in chapter 5 and that it is probably near the beginning of the chapter. There will be about 40 questions on the mid-term (some from here, some from your quizzes, and some that have not been seen before.) Try taking this review as a timed test to get a feel for pacing. I would normally allow about 2 hours for this test. Multiple Choice Identify the letter of the choice that best completes the statement or answers the question. ____ 1.
