I like open and free classMy favorite class is an open and free class. In this kind of class, I can learn by myself and discuss in groups. It is good for my development, I think.I still remember an unforgettable experience in my maths class. Several days ago, I spent a long time working on three difficult maths problems in class, but I still couldn’t work them out. So I had to ask my classmates for help. After a considerable discussion, we solved the problems in our group. I felt very excited!That was a great experience, so I want to give two suggestions. Firstly, please don’t teach us too much in class. We need about 30 minutes to learn by ourselves and work in groups every class. Secondly, please provide us with some laptops if possible, so that we can surf the Internet easily. No doubt, we need an open and free class, you see.
