Dear Mary, I'm sorry to hear that you didn't get good grades in math mid-term exam. And you said you spend a lot of time studying math. However, it is difficult for you to learn it well. I think you should find a right way to learn it. Here is my advice for you. During the class * Listen to the teacher and be sure to write down everything the teacher puts on the blackboard. * If you don't understand a step or how to get the answer to the question, ask the teacher or a classmate for help right now. * Underline key points while taking notes. After the class * Recopy each day's notes into a new notebook clearly. * Do your homework every day carefully. And don't copy other students' homework. * If a step is unclear or you don't know how to do it, ask for help soon. _  * Look for useful examples of how this kind of difficult problem is used in your textbook or other materials  Before exam * Review  all of your notes quickly and find out every missing problem at times. * Work examples in the text each several times until you can do them quickly. This will help you improve the speed  needed for the exam. If you do as I said, I think you will get good grades in the final exam. Come on! Mary. Which of the following ways is not mentioned in the passage?
Be sure to write down everything the teacher puts on the blackboard. Underline key points while taking notes during the class. Work examples in the text each several times until you can do them quickly before the exam. Put up your hand if you don't know how to do it.
