I suggest that nothing is like a three-year simulation of the five-year college entrance examination. He has classified, and there are many problems you can do. You don't have to do everything on your personal basis. The college entrance examination questions should be repeated! As a candidate who finished the exam, I personally practiced the saying that there will never be original questions in the college entrance examination, but the quality of the college entrance examination questions in previous years is also the highest. The knowledge points that have been tested are tested year after year, and other messy questions don't need to be done more. The really effective questions are simple questions and intermediate questions. The problem is that you thought of it yourself and can't do it. You can only do a little bit similar, that is, the first question of the question is to send sub-questions. The school will give you other messy questions, don't buy them.
