During the exam, I signed up for Schwartz. It's good for the public class teacher to go to the scene to listen. There are many people in class, and the scene will be more atmosphere. The video version that students listened to at school didn't work very well. To tell the truth, Jia Xinnuo did quite well in several classes he took. The quality of the handouts and papers used in the exam is very good, which is better than other papers and comfortable to write. What you say upstairs depends on your own foundation. I think it's best to report intensive lectures and eye-catching classes during the summer vacation. Intensive lectures can explain some basic knowledge to you clearly, and eye-catching classes can re-plan the focus. I am a liberal arts student. The political effect is very good, and it is very organized for me. I don't know English at all, so it doesn't help much. Students report that math is good, depending on whether you pay attention to it yourself. It will be useful if you listen carefully. The last model exam class was useless, and it was difficult to write a paper that day.
