Reseña del libro "Practice to Mastery (en Inglés)"
Practice to Mastery: AP® Macroeconomics Practice Exams gives students twelve complete, full-length practice exams for the AP® Macroeconomics Exam. Each one is built to the published structure of the current exam, written to the scope of the current course, and followed by a full answer section. Together they hold 756 original questions, 720 multiple choice and 36 free response, every one with a detailed explanation or a point-by-point scoring guide.Twelve exams built like the real oneEvery exam follows the official format. Section I has 60 multiple-choice questions in 70 minutes and counts for 66.65 percent of the score. Section II has three free-response questions in 60 minutes, including a 10-minute reading period, and counts for 33.35 percent: one long question worth 10 points and two short questions worth 5 points each. A four-function calculator is allowed. Each exam spreads its questions across the six course units in proportion to their published weightings, so every paper gives a balanced picture of readiness.Questions that test reasoning, not recallThe exam rewards students who can follow a change through the economy, step by step. These questions do the same. They ask students to identify which curve shifts and why, to carry the effect to output, the price level, interest rates, and exchange rates, and to compare the short run with the long run. Data tables, graphs, and question sets built on a shared scenario appear throughout, just as they do on the real exam.Free-response practice with correctly labeled graphsEach Section II combines several units in the way the exam does, and each includes graphs and calculations. The scoring guides show exactly what earns every point, note the answers that commonly lose it, and give a model response. Every model graph is fully labeled, with both axes, every curve, each equilibrium, and the direction of every shift marked, so students can check their own graphs label by label.Answers that teachEach Section I explanation names the unit the question comes from and works through the reasoning that leads to the correct answer, so a missed question becomes a lesson. A score-estimation guide at the end of every exam converts results into an estimated AP® score, so students can track their progress from one exam to the next.How to use this bookThe preface explains how to sit each exam under timed conditions, how to score Section II honestly, and how to keep an error log that sorts mistakes by unit and by type: graphs, calculations, explanations, and chains of reasoning. Spaced a week or so apart with review in between, the twelve exams form a complete final-preparation program for the weeks before test day.All content is original. The exams cover every major topic in the course, including GDP, inflation, and unemployment; aggregate demand and aggregate supply; the spending and tax multipliers; fiscal policy; money, banking, and monetary policy in an ample-reserves system; the loanable funds market; crowding out; the short-run and long-run Phillips curves; economic growth; the balance of payments; and the foreign exchange market.Practice to Mastery is a series of AP® practice books written by Jiazheng Chen. The companion volume, Practice to Mastery: AP® Macroeconomics Workbook, provides unit-by-unit practice organized by the six course units. No question is repeated between the two books.AP® and Advanced Placement® are registered trademarks of the College Board, which was not involved in the production of, and does not endorse, this product.
