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. After class, I did a lot of exercises. 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. At first, I asked my math teacher and my teacher for help, but later, I didn't want to do it again because I thought it was useless. I'm so tired. I don't want to study math anymore.
