The score on the test if you get 8 out of 73 wrong can be calculated by subtracting the number of wrong answers from the total number of questions and then dividing the result by the total number of questions and multiplying by 100 to get the percentage score.
Incorrect Answers = 8
Total Questions = 73
Score = [(73 - 8)/73] * 100 = 0.8836 * 100 = 88.36%
Therefore, the score on the test if you get 8 out of 73 wrong is 88.36%.
