For the clue that you didn't do the problem, 1 means that you didn't do the problem. 2. Your knowledge is not systematic. You don't understand the teacher's intention.
When doing a problem, you should do a classic problem, that is, a problem with many different knowledge points, and then follow the routine. Some problems are solved regularly, that is, if you can't do one-on-one training on any topic (in fact, sea tactics)
It is strongly suggested that a knowledge system can be formed, that is, a lot of divergent thinking can be brought out. It is best to say what you have learned when you close the book, so that you can dissect the topic and analyze it clearly one by one.
You can try to guess the teacher's intention to write a question, which is actually a question that students like to confuse. The more you guess, the more you understand (you can even try to write a test paper yourself). At that time, you will stand at a height to do the problem, not do it for the sake of doing it.
Finally, the simpler the questions, the more secure they will be, which will improve your self-confidence in the exam and ensure your high score (after all, a large part of the questions in the college entrance examination are simple)
The above is my experience. I hope it helps you. I got more than 130 (science) in the college entrance examination that year, although it was not very high.
Finally, I believe I can do it. After such a long training, you can.
Finally, I wish you good results in the college entrance examination.
