1) I want to have the math lesson more than six times a week, because this subject is really hard for me and I want to learn it better and harder. I found this subject really exciting.
2) I would like to have the biological classes more than twice a week. I think, it's really amazing when you learn more about the world around us.
3) I want to have the classes of english language five times a week, because now this language helps us to communicate with each other.
