How Your Final Exam Score Will Be DeterminedThe table below shows how raw scores on the ACS exam will be converted to scaled final exam scores.The ACS standardized exam has 70 questions.In the event you are unfamiliar with how percentiles work, an 84 th percentile means that you scoredhigher than 84% of the students on the national norms and a 25 th percentile means that you scoredhigher than 25% of the students taking the same exam on the national norms. Students scoring in the80 th to 100 th percentile will be assigned an "A" score on the final, the 60 th to 79 th percentile will beassigned a "B", the 40 th to 59 th percentile will be assigned a "C", the 20 th to 39 th percentile will beassigned a "D", and the 0 th to 19 th percentile will be assigned an "F".RawScorePercentileRankingScaledPercentageScaled FinalExam Score70 100 100 20069 100 100 20068 100 100 20067 100 100 20066 100 100 20065 100 100 20064 100 100 20063 100 100 20062 99 99.5 19961 99 99.5 19960 99 99.5 19959 98 99 19858 97 98.5 19757 96 98 19656 95 97.5 19555 94 97 19454 93 96.5 19353 91 95.5 19152 89 94.5 18951 87 93.5 18750 85 92.5 18549 82 91 18248 80 90 18047 77 88.5 17746 74 87 17445 71 85.5 17144 68 84 16843 65 82.5 16542 62 81 16241 60 80 16040 57 78.5 15739 54 77 15438 51 75.5 15137 47 73.5 14736 44 72 14435 41 70.5 141RawScorePercentileRankingScaledPercentageScaled FinalExam Score34 38 69 13833 35 67.5 13532 32 66 13231 30 65 13030 27 63.5 12729 24 62 12428 22 61 12227 19 59.5 11926 17 58 11625 14 55 11024 11 53 10623 9 50 10022 7 48 9621 6 47 9420 5 46 9219 3 45 9018 2 44 8817 2 43 8616 1 42 8415 1 41 8214 0 38 7613 0 36 7212 0 34 6811 0 31 6210 0 28 569 0 25 508 0 23 467 0 20 406 0 17 345 0 14 284 0 11 223 0 8 162 0 5 101 0 2 40 0 0 0
