The best way is to buy a set of green cards, one for each course. Let's take a look at the key points summarized in this chapter of Knowledge Encyclopedia, and don't have to understand them all. Remember why this chapter is so general, what is the structure of knowledge points and what is the key point. Then search the courseware of the same chapter on the internet and look at the teaching materials against the courseware. Generally, it takes about a month to teach a course by yourself, and it will be very hard to compress it to 100 days. To do this, you must be a student with a strong memory, otherwise when you study chemistry, mathematics and physics will be forgotten; When studying biology, I forgot chemistry again. . . Geniuses in some schools can take the college entrance examination as soon as they finish their first year of high school, and they can get more than 650 points. Such students all study in advance.

If you relax the time a little, half a year, one year, that's no problem. For example, if you concentrate on studying mathematics for 2-3 months, you won't have to learn the basic knowledge for the remaining 2 years. Listening in class is equivalent to reviewing. In the last two years, you can read college textbooks, take part in the Olympic Games for senior high school math and science students, and find a question bank like May 3rd to conduct sea tactics to see how these knowledge points come up.

Some people may think it is exaggerated, because you have never studied like this and have never met a good student. Students in other Olympic Games classes have finished their high school courses in junior high school, some high school students have finished some college textbooks, and some can even take part in the Olympic Games. The bookcases at home are all kinds of university textbooks and popular science books, which are neatly arranged in different categories. Such students have smart brains and strong understanding of learning methods! In fact, speaking carefully, I have emphasized the central idea of induction from the primary school Chinese class and summarized it ... But how many people can really apply it to learning?
