* * * 54 multiple-choice questions, the correct number minus the wrong number times a quarter, plus the correct number of fill-in-the-blank questions, rounded to the nearest integer to get the original score. Then the original score is converted into the final score of 200 ~ 800 points through the conversion table (adjusted according to the difficulty of the exam every time).

Therefore, if all the candidates get 54 questions correctly, they can certainly get full marks in SAT mathematics. However, due to the low mathematical fault tolerance rate, 1 is 780, 2 may be 750, and 3 may be 7 10. Therefore, it is very wrong to deduct points from mathematics. According to statistics, the average score of China students in mathematics is around 750.
