Can I use chalk for the recruitment exam?

The course of chalk teaching comprehensive system is not as good as its book, and the focus is on the "problem-solving skills" of teaching comprehensive system. Sometimes the knowledge points are not detailed enough, and I always show off my skills when teaching various problem-solving skills. Friends who don't know anything may think it's really amazing. It's really cool to help me get points quickly. . . But what I want to say is! Chalk skills are really fancy, but for Xiao Bai, he will still forget the knowledge points after reading the questions (the knowledge points in the teacher's class are a little deep, after all, they are not specially used for memory)
