Compared with junior high school, the proportion of multiple-choice questions in high school science subjects is larger, accounting for about 40% of the total score. The multiple-choice question score rate has a huge impact on the final score.
Mathematics has a total score of 150 points, with 40 points for single choice and 20 points for multiple choices. Each question reaches 5 points, which is close to a big question (12 points for big questions, 6 points for each question). Different from the step-by-step scoring for big questions, multiple-choice questions only have right or wrong.
For middle school students, it is difficult to score more than 50% on major questions, and the score on multiple-choice questions is particularly important.
8 single-choice questions: 1-6 questions will be scored, 7 questions are medium, 8 questions are difficult, 30 points are guaranteed, 35 points is a good score, 40 points depends on a certain amount of luck.
Questions 6 and 7 have a higher distinction between and for middle-level students, which is where the gap between students of the same level lies. The 5 to 10 points difference in the total score often lies here. If question 8 is too difficult, you can just rely on your feelings. Ensure maximum completion of the entire test paper.
Multiple-choice: Multiple-choice has appeared in mathematics in recent years. Multiple-choice does not score points, and the score for less-choice is the biggest variable of multiple-choice. A multiple-choice question in mathematics usually has four options and four operation directions, which need to be verified one by one. There will not be a situation where A is selected and B is excluded like in physical chemistry. For example, trigonometric function can examine computational reasoning from different directions such as periodicity, parity, and function translation.
The first two questions are relatively simple. Try to make sure that they are all correct. If you can only calculate two answers, it is better to put 5 points in your pocket. If there are three answers, be extra careful and spend more time to verify. The most important thing is to ensure that you score. If you are sure of three answers, you do not need to give up and get them. Three points. If the third answer is uncertain, decisively giving up to save two points will still have a chance to get 5 points. Assuming that the third answer is 40% likely to be correct, the average scoring rate of Jiuwei for choosing two answers is 5X40%+2X60%=3.2 points, and the average scoring rate for choosing three answers is 5X60%=3 points. Even if the probability is 60%, the two answers are still more cost-effective.
The last two questions are slightly more difficult, especially the last question. Choosing only one question to save time and save two points is the wisest choice.
For intermediate students, 12 points for multiple-choice questions is acceptable, and 14-15 points is a better result.
Another thing to note is that math multiple-choice questions do not need to be calculated by hand. Proficient skills in number substitution and option elimination can achieve twice the result with half the effort.
Mathematics fill-in-the-blank questions are also 5 points each, totaling 20 points. Compared with choices, fill-in-the-blank questions require hard calculation skills. For questions that you know how to do, it is recommended to calculate it twice more to ensure that you get 5 points. Multiple-choice questions have options to confirm, big questions are scored step by step, and fill-in-the-blank questions are a one-time deal. Any mistakes will not count for 5 points. More importantly, the fill-in-the-blank questions must be written clearly.
