If you get good grades in junior high school mathematics and want to take the initiative, you will learn better from the second day of junior high school. What grade are you in now? Putuo's new trump card has opened independent enrollment classes since the second day of junior high school, and their independent enrollment classes also have handouts specifically for independent enrollment. Basically, the content of self-enrollment will be very similar to the competition, and it will include the content of the senior high school entrance examination, but it will not cover as much as the competition. Mathematics is to do more problems, so as to draw inferences. Anything you don't understand and can't be dealt with in time, the big questions at the back of the test paper are the most important.
