Of all the subjects I studied at school, I like math the least because it is too difficult to learn. In class, I listen to the teacher carefully. I do a lot of exercises after class. But I still have many problems in learning math. Sometimes, I learned it in class, but after class, I completely forgot it. It bothers me. First, I asked my math teacher and classmates for help. Gradually, I don't want to anymore, because I feel useless. I'm so stupid. I don't want to study math anymore.
