Dear teacher:

Hello:

After this math exam, I deeply realized my own shortcomings. I know my math (maybe it's the wrong learning method and bad time arrangement. I should think more about the nature of the problem at ordinary times. Maybe these reasons? I think there are several reasons why my math scores are so poor this time. I will try my best to improve next time. At the same time, I hope teachers can do some bad things in class. If there are any suggestions, I can make some appropriate suggestions. )
