Practice Test 2 PHYSICS PHYSICS PHYSICS PHYSICS PHYSICS TESTTEST TESTTEST TEST Peterson’s: www.petersons.com 273 PRACTICE TEST 2 PHYSICS PHYSICS PHYSICS PHYSICS PHYSICS TESTTEST TESTTEST TEST While you have taken many standardized tests and know to blacken completely the ovals on the answer sheets and to erase completely any errors, the instructions for the SAT II Physics Test differ in an important way from the directions for other standardized tests. You need to indicate on the answer key which test you are taking. The instructions on the answer sheet will tell you to fill out the top portion of the answer sheet exactly as shown. 1. Print PHYSICS on the line under the words Subject Test (print). 2. In the shaded box labeled Test Code fill in four ovals: —Fill in oval 1 in the row labeled V. —Fill in oval 6 in the row labeled W. —Fill in oval 3 in the row labeled X. —Fill in oval C in the row labeled Y. —Leave the ovals in row Q blank. V W X Q Test Code Subject Test (print) Physics 12 3456789 12 3456789 12 3 4 5 AB CDE 12 3456789 Y There are two additional questions that you will be asked to answer. One is “How many semesters of physics have you taken in high school?” The other question lists courses and asks you to mark those that you have taken. You will be told which ovals to fill in for each question. The College Board is collecting statistical information. If you choose to answer, you will use the key that is provided and blacken the appropriate ovals in row Q. You may also choose not to answer, and that will not affect your grade. When everyone has completed filling in this portion of the answer sheet, the supervisor will tell you to turn the page and begin. The answer sheet has 100 numbered ovals, but there are only approxi- mately 75 multiple-choice questions on the test, so be sure to use only ovals 1 to 75 (or however many questions there are) to record your answers.
