1, multiple-choice questions: Generally speaking, the first few questions of multiple-choice questions are very simple. You can put the options into the question one by one, and you can choose the one that you think is correct. According to statistics, the number of times that 17 multiple-choice questions and any option of ABCD become the correct answer is 3-5 times. I can only write 1-2 questions, and the remaining 15 questions are different from the answers I know, so I can get at least 20 points. For example, if you can write a question and choose a question, you can write C or D for the question that 15 doesn't know how to write it.
2. Fill in the blanks: Compared with multiple-choice questions, there are no options for reference. What should I do? Let me give you a hint. Generally speaking, there is a high probability that the answers to multiple-choice questions will be 0, 1 and 2. If you can't do it, just put these three numbers in it. If you think it's right, fill in that. Don't fill in all the same items, and the multiple-choice questions above are the same. You can't select the same item, otherwise 0 points.
3. Solution: First of all, you write the word "solution", write this word 1, and you will get 1-2 points. Then list the formulas, similar to this topic. Write as much as you want, so that the teacher will give you 2-3 points whether it is right or not. So you can get about 3-5 points, and of course you can write down the answer later. The middle step is to modify the formula you wrote, as much as you can.
