**MATHEMATICS LEVEL 1 TEST FORM A**

For each of the following problems, decide which is the BEST of the choices given. If the exact numerical value is not one of the choices, select the choice that best approximates this value. Then fill in the corresponding oval on the answer sheet.

__Notes__: (1) A scientific or graphing calculator will be necessary for answering some (but not all) of the questions in this test. For each question, you will have to decide whether or not you should use a calculator.

(2) The only angle measure used on this test is degree measure. Make sure that your calculator is in degree mode.

(3) Figures that accompany problems on this test are intended to provide information useful in solving the problems. They are drawn as accurately as possible EXCEPT when it is stated in a specific problem that its figure is not drawn to scale. All figures lie in a plane unless otherwise indicated.

(4) Unless otherwise specified, the domain of any function *f* is assumed to be the set of all real numbers *x* for which *f*(*x*) is a real number. The range of *f* is assumed to be the set of all real numbers *f*(*x*), where *x* is in the domain of *f*.

(5) Reference information that may be useful in answering the questions on this test can be found below.

THE FOLLOWING INFORMATION IS FOR YOUR REFERENCE IN ANSWERING SOME OF THE QUESTIONS ON THIS TEST.

**HOW TO SCORE THE PRINCETON REVIEW PRACTICE SAT MATH SUBJECT TEST**

When you take the real exam, the proctors will collect your test booklet and bubble sheet and send your bubble sheet to New Jersey where a computer looks at the pattern of filled-in ovals on your bubble sheet and gives you a score. We couldn”t include even a small computer with this book, so we are providing this more primitive way of scoring your exam.

**Determining Your Score**

**STEP 1** Using the answers on the next page, determine how many questions you got right and how many you got wrong on the test. Remember: Questions that you do not answer don”t count as either right answers or wrong answers.

**STEP 2** List the number of right answers here.

**STEP 3** List the number of wrong answers here. Now divide that number by 4. (Use a calculator if you”re feeling particularly lazy.)

**STEP 4** Subtract the number of wrong answers divided by 4 from the number of correct answers. Round this score to the nearest whole number. This is your raw score.

**STEP 5** To determine your real score, take the number from Step 4 above and look it up in the left column of the Score Conversion Table on __this page__; the corresponding score on the right is your score on the exam.

(A) ______________

(B) ______________ ÷ 4 = (C)______________
