I'll tell you a secret. High number is as simple as death. I mean high A, Tongji Edition (most schools should use this). It's just that there are too few explanations in this book, which makes people who want to teach themselves advanced mathematics through this book a headache.
My method is to watch the ppt of advanced mathematics class, which is easy to understand, comprehensive in content and clear in explanation. You can usually watch several classes at a time. After reading a chapter, I can do the exercises in ppt. Basically, ppt involves solving problems, but it's not your problem that I can't do it. It is the teacher's mistake, which belongs to the teaching accident.
Of course, there will always be one or two questions stuck in the process of self-study, and this time is also very simple. Ask those who are preparing for the postgraduate entrance examination in junior year (you can study with them and ask questions directly). Mathematics for postgraduate entrance examination is more difficult than advanced mathematics (advanced mathematics is for children who have just entered college). . ), as long as the learning level is medium, it is quite naive to solve your problem of high mathematics. The so-called expanding exercises and thinking questions given in ppt are just classic questions of mathematics for postgraduate entrance examination over the years, which is not difficult.
When you finish watching ppt and do the corresponding exercises, the study out of interest can be over. For the emergency final exam, you need to do the real questions in previous years, find the weak points, and practice more questions. Of course, it is not enough to take the postgraduate entrance examination for mathematics, but also to learn line generation, statistics and so on. Find a teaching assistant to chew it yourself. .
As for the study time, the average time is 2-3 hours a day: 1 month, I can learn very well, thoroughly understand the teaching materials, and can do related topics for postgraduate entrance examination; Meet the final exam needs 10 days; Out of interest, depending on how much you want to learn, the time is between the first two. (I mean learning a book)
The above is a summary of personal experience, hoping to help the landlord.
