The classification of teaching AIDS is mainly aimed at different stages or learning requirements, and the learning objectives and requirements of each stage are different, so correspondingly, teaching AIDS are also selected in stages.

When it comes to supplementary books, it's never the so-called "testing the gods", Rainbow Hou Xiong. Take Wang Houxiong as an example. I know his supplementary series is:

First, synchronous classes (one-to-one correspondence with different versions of textbooks and courses around the country)

Complete interpretation of teaching materials (the ratio of lecture to practice is 7: 3), complete learning plan of teaching materials (focusing on practice, which can be regarded as an exercise book matching the complete interpretation of teaching materials) and complete interpretation of classes (the ratio of lecture to practice is 5: 5).

Second, the general review class

Senior three: a complete interpretation of the college entrance examination, with college entrance examination 1 vs 1 and college entrance examination 12 respectively corresponding to the first, second and third rounds of review in senior three.

Third, others.

"600-point topic" (special study and training), "600-point problem-solving encyclopedia" (high school grades, mainly explaining the problem-solving methods), "Exam must be remembered" (booklets written with useful knowledge points in junior and senior high schools) and so on.

These books are only used to illustrate that different books should be used at different times and stages, because these books are aimed at different learning stages and different learning requirements. It can be seen that teaching AIDS are either used for synchronous learning corresponding to courses or for review; The content is either a summary of knowledge points or a collection of exercises or papers ... so it is unlikely that there will be a book devoted to multiple-choice questions, fill-in-the-blank questions and the last big question, because these questions will test different knowledge points, and you should be able to cope with them if you understand the knowledge points.

Because Baidu knows that you can't send links in the website, or you can read e-books, you will understand what a section is and what a content setting is. You can only search by yourself, or go to a physical bookstore to read books. It is best to choose your own grade and stage.
