(42-3)/42 = 39/42 = 92.9%
A test score of "90" represents the percentage of correct questions. Multiply this percentage by the total number of questions and you will have the number of questions correctly answered. Subtract this from the total to find answers wrong. 90% of 40 questions = .90 x 40 = 36 questions right. 40-36 = 4 answers wrong.

To figure out your score on a test, you just have to divide the number of answers you got right by the number of total questions there were. In this case, 65 divided by 73= .89 or 89%.
I'm not exactly sure but I know that I got at least 2 questions wrong on the Chinese SAT II and I still got an 800. I suppose it all depends on what questions you got wrong.

Your score on a test is based on the number of questions answered correctly, so the score is 35/47 = about 75%. The letter grade for that score is completely the teacher's decision.
In the PSAT, just as in the AP and SAT, if you guess at an answer and get it wrong you lose one quarter of a point. For each question you answer correctly, you gain one point. Therefore if you got 4 questions wrong and one right, you would have a total score of zero. If you had skipped those 4 questions you got wrong, you would have a total score of one.
80-14=6666/80=0.825 =82.5%
If each question is worth one mark you would have received 81% 85-16=69 69/85= 0.811 x 100 = 81%
