However, I suggest you communicate with your classmates more. First of all, although the course is only one month, it is certainly beneficial for everyone to get along with each other in the same class day and night, and may even bring you unexpected gains. In addition, since everyone is studying makeup, it is very likely that they will all be colleagues in the future, and then they will often deal with each other in the circle. It will be good for you to accumulate contacts now.
It takes time and skill to get along with people, so exercise slowly!
