As mentioned just now, online comments are not true or false, so seeing is believing. I suggest that I spend some time and do more field trips to get real information. A very effective method of field trip is to listen to the class directly (instead of attending an open class). In this way, you can directly feel the real teaching atmosphere of the school and feel the teaching methods of the course. A really good school will definitely provide this kind of service.
In addition, you can communicate with your old classmates at school, and the information you get is much more reliable than online. Official website's detailed course information should also be checked by yourself to see if the query is reasonable and helpful to study.
In a word, these jobs may be troublesome. However, it will definitely be good for your future study career. If you are not careful, you will suffer.
