Note taking is one of the most important skills to crack TOEFL. This technique if relearned well can fetch you really good scores especially in Reading and Listening section. We mentioned relearn because note taking technique that you might have learned in school days might not be good enough. Purpose of taking notes in school days was to either jot down important points which you can remember later in order to recreate your answers or to condense a chapter. In TOEFL, you are not only supposed to meet before-mentioned purpose but also apply it aptly in producing answers of the questions in limited time.
Have a purpose
Do not take notes just for the sake taking it. Think of the purpose of it. In case of Listening section, if you are supposed to solve Multiple Choice Questions after listening to the recording, take notes accordingly. You need to jot down ideas explained in few keywords, not in descriptive format. This will save time and also help you do justice to all points. In case you need to speak after listening to particular piece of audio, take notes in such a way that you can go back to each point and add few extra points that you -would like to add. This will save your ample of time allotted to prepare to speak.
Pay attention to tone or actions
This question is fairly common on TOEFL. After reading a passage or listening to the audio you might be asked to select tone or follow up action after conversation. While reading or listening try to judge mood of author or speaker and jot it down after the notes taking session.
Create a format
After sufficient amount of practice you will be able to generate you own format which will help you in variety of questions. You may have two columns while taking notes. In one of the columns you would like to take notes while to other column you might like to add your own ideas.
