2. Mathematics High school mathematics is very different from junior high school mathematics, and high school mathematics cannot be limited to textbooks. The concepts in the textbook should not only be memorized, but also understood. I can say that 90% of the exercises in the textbook are basic questions, and such questions are hardly tested in the unified examination and college entrance examination. Both the college entrance examination and the college entrance examination come from textbooks, but they are higher than textbooks. If you can't understand a concept, you can't do it. In addition, high school mathematics is closely linked. If a link is broken, it will become a big problem in the future, and it should be consolidated in time. If you have time now, you must understand the concept carefully and do some typical exercises. Don't just look at simple topics and don't do it. If you only look at the topic for a long time and don't do it, your hands will be rusty, and mistakes such as clerical errors will easily occur when you take the same topic in the exam. When school starts, you will find that the math teacher is very fast in class. You have to take two compulsory books in the first semester of senior one, and you can imagine the speed. You don't have the energy to study math for a long time.
