1) Postgraduate entrance examination is a hard process, mainly relying on yourself, the role of remedial classes, just saying that it is a guiding thing for people who have no experience in postgraduate entrance examination, which can make you take fewer detours, but it is by no means your crutch. The most important factor is the candidates themselves, who play a decisive role. The higher their personal efforts, the more likely they are to be admitted to graduate school. So instead of muddling along, it is most practical to calm down and work hard. Since I chose the distance, I chose to share joys and sorrows, stick to what others can't insist on and achieve what others can't achieve!

2) No matter whether the class is an interview or an online lecture, the content that the teacher talks about every year is the same, and those lecture videos are all found online.

3) It is inefficient to report to class and waste a lot of time. Moreover, teachers in graduate classes generally like to talk nonsense for a long time. It seems that this class is boring without a few jokes.

4) Waste of money, the cost of ordinary postgraduate entrance examination is relatively high, which increases the burden.

5) The biggest advantage of applying for classes is only psychological effect, but it is only psychological effect, that is, spending money to buy comfort.
