Teaching materials help is a complete set of teaching materials, which combines teaching with practice and focuses on explanation. The test questions are relatively new, and the number of questions is quite large. All the questions I can't do on the exercise paper after class can be found in the help of the textbook, and some of them are original questions. In terms of content, I think the steps to solve the problem are also clear and the methods are easy to understand. I think I can really buy one, which is very helpful for learning new lessons. More than half of the students in our class have bought them, and our math and English teachers are also using them. Courseware seems to be a courseware with the help of teaching materials. Give it to us after revision. Therefore, if you want to buy teaching materials, it is right to choose "Teaching Materials Help". I'm happy to answer your question.
