Simply put, the advantages of chalk are low price, online teaching, and no geographical and spatial restrictions; The disadvantage is that it is difficult for teachers to play a supervisory role and there is less interaction; Chalk online teaching is really cheap and convenient, but because there are many people watching it, it is difficult for teachers to communicate with every student. Teaching is a two-way process, but in chalk, this process is one-way.
At the beginning of the foundation of the public examination, I searched online first, and all kinds of dry goods were recommended, which was dazzling. After saving some seemingly dry materials, I think we should study comprehensively according to the basic courses, because these shared materials are fragmentary and suitable for reading again as a basis.
In order to choose more books and chalk online courses. That's how I learned it when I took the exam. Zhonggong's books are more comprehensive. I didn't buy a chalk book, but there are chalk lines in class. I took the primary school exam and basically looked at the comprehensive quality from beginning to end. Because time is tight, I haven't read any books in subject two, so I have been watching online classes and brushing questions. Do a set of questions on the paper, correct the wrong questions in time and analyze them carefully. It is really important to brush questions on the chalk APP in your spare time, especially before going to bed at night.
