Write clearly in the space provided on this Answer Sheet the letter which you believe to be the best answer to each question on the Mini-Test and on the Final Exam, found on the following pages. Neither calculators nor notes can be used during the test. Each question on the End-Material Mini Test is worth 10 points, and on the Final Exam 6 points. Relax, Read carefully, Think S and then read it again!!! If you become bogged down on a problem, go to the next one and return later to the hard one. Think before plunging into math manipulations. Basic principles may give you an easy answer. Never leave a multiple-choice question blank. Guess at the end if you must. EM Mini-Test Score = Mini-Test Responses (10 pts each) Final-Exam Score = Final-Exam Responses (6 pts each) em - 1) 1) 16) em - 2) 2) 17) em - 3) 3) 18) em - 4) 4) 19) em - 5) 5) 20) em - 6) 6) 21) 7) 22) 8) 23) 9) 24) 10) 25) 11) 26) 12) 27) 13) 28) 14) 29) 15) 30)
