What have I done to improve on my exams

To improve on my examinations, I have been practicing my homework regularly in order to get a good grade. My mother also helps me to revise what I have learnt in school. I am trying not to give myself too much stress or give my self a heavy load. My parents remind me to sleep early on the days I am going to have my exams. I have promised them that I will get a good grade. I really, really hope I will get a good grade.
