Today I’m going to introduce some effective skills for taking notes. Before making suggestions I’d like to analyse some factors that can affect note-taking. Of course the first one is your vocabulary. An instructor cannot spell all words in class. So it is necessary for students to master a massive vocabulary, especially for non-native students of English language. Second, good psychology is also important for note-taking. Some students are very nervous in class and cannot follow the instructor in time although they have a good ability to take notes. Well, what skills can help you improve the ability and the speed of note-taking?
    Let’s begin with the first one of five steps. As usual, students can get course handouts in advance. Preparing for them will help you know about what the instructor will talk about in class and then help with your note-taking.
    The second step is to put a date and a title on the first page. This will help you make sure about the lecture topic and the class in which the note is taken. Some students also think this is very important for their studies later. And then I advise you to use a divider which can set aside different parts in one notebook. For example, drawing a line in the middle of the notebook and then write main points on the left and some extra information on the right.
    And now for the third step. In class a good note-taker should only write key points, not all the information. Some students cannot understand what they wrote on notebook after class. So how to master key points is very important. These points are usually nouns, adjectives, verbs and numbers. Writing only one to two points on each line can help you to understand the notes when you read them later.
    The most difficult part for nearly all students is, of course, to have enough time to write the notes. So the next step is coming. In order to save time and speed up writing, I advise you to use abbreviations and symbols instead of words. When your instructor speaks loudly or repeats some contents or has a short pause you should pay attention to the points related.
    The last suggestion is that you should review your notes after class when the information is still fresh in your mind. Try to summarize the key points and check notes with your classmates after class.
    I hope all these can help you with your note-taking in class.
