It is a foreign textbook. In general English class, we will talk about nature, humanities and mathematics.

It is very interesting to study all kinds of subjects like that.

I also go to lectures when I am free.

I feel that their teacher is very powerful. At least in class, it's just language communication, and children are very interested in learning. You can go and have a look, and it's not bad to attend classes for free. You can also audition.
