I tell you from my personal experience that it is still useful to apply for the training edition. I took the exam twice before and got more than 50 points. I have brushed a lot of questions myself, and I have never made progress. Later, I asked a lot of people and looked up a lot on the Internet. Finally, lock the chalk and praise the public exam. After listening to the course, I chose to praise the public exam. I think I like Mr. Climbing Jun's lecture style. He praised the public exam. It is lively, dull and rhythmic. I learned a lot of problem-solving skills, and the most important thing is the learning method. The teacher will talk about how to learn each part, what is the key point of learning, and finally brush the questions according to the method the teacher said, which makes great progress. Both the test and the application are 70 points, because the written test score is very high, so the interview is very easy.
