American Diploma Project ALGEBRA l End-of-Course Exam PRACTICE TEST Student Name: __________________________ General Directions Today you will be taking an ADP Algebra I End-of-Course Practice Test. To complete this test, you will need to use the answer document provided with this practice test. This practice test is designed to simulate the ADP Algebra l testing experience. Your test will not be scored at Pearson. However, an answer key is provided to check answers. This test consists of two sessions. During Session 1, you will NOT be allowed to use a calculator. During Session 2, you will be allowed to use an approved calculator. Three different types of questions appear on this test: multiple-choice, shortansswer and extended-response. The response area for short-answer questions is about one-half page, and the response area for extended-response questions is about one page. While taking this test, remember: 1. Read each question carefully, including diagrams and graphs. 2. For multiple-choice questions, choose the best answer from the four choices given. Mark only one response for each multiple-choice question. 3. For short-answer and extended-response questions, write your answers in the gridded box provided in your answer document. You do not have to use all of the space provided. Although a gridded answer space is provided, you will not need to graph answers to all extended-response or short-answer questions. Answers may be graphs, text, or calculations. 4. If a short-answer or extended-response question asks you to show your work, you must do so to receive full credit. If you are using a calculator, describe the calculation process you used in enough detail to be duplicated, including the numbers you entered and the function keys you pressed to find the answer. If a short-answer or extended-response item has multiple parts, label each section of work and clearly identify your answer for each part. 5. Be sure to answer all questions before you end each test session. However, do not spend too much time on any one question. If you do not know the answer to a question, make your best guess and go on to the next question. You will not be penalized for guessing. 1 Please Go On To The Next Page ADP Algebra I End-of-Course Practice Test Session 1 Calculator NOT allowed Session 1 Session 1 Directions You may NOT use a calculator in this session.
