Reading: subtract the correct number from the wrong number and multiply it by a quarter, then round it to the whole number 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).
Mathematics: multiply the number of mistakes by a quarter, subtract the correct number of multiple-choice questions, and add the correct number of fill-in-the-blank questions. The algorithm is similar to reading.
Writing: After subtracting the number of errors from the correct number of multiple-choice questions and multiplying it by a quarter, round it to the nearest integer to get the original score of multiple-choice questions, then merge it with the score of composition (0- 12) and convert it into the final score of 200-800 points through a conversion table (adjusted according to the difficulty of the exam each time).
