My first class every morning is Maths. I am understanding what the teachers says, but when I try to do the exercises, i am not remember anything! When the teacher ask me , i am always saying, i an sorry but i have got a headache. Of course he isn't believing me. He is thinking that i don't study very hard, but i do study every night. Something happens to me when i go into the class. We've got a test this week, and I'm being really worried!What are you thinking I should do?i really like the teacher and i want to do well/ I am needing help, and fast! Помогите поставить глаголы в правильное время!!
