Resume? It's easy to find. If the internet is 100 degrees, it is only a handful. There must be something you can refer to. The job of teaching assistant mainly depends on your ability to express and organize activities. You can talk about what you have done as a class cadre and what you have gained, for example, class first, and so on. They don't want to recruit a student who can only study. It is best to be a class cadre, or to organize any activities at school, but it is better. Because this thing is similar to the position you want to apply for, in fact, finding a job in a university is also the same idea. Good luck!
