Just the act of taking notes and reviewing them improves your understanding of the material. View your note taking as your first layer of study.
At first, you may believe that you aren’t cut out to write notes or that you’ll have no problems remembering what was said. None of that is true. So, listen and write. Read and write. Your comprehension skills and listening skills WILL IMPROVE.
Don’t despair if you cannot catch every word or you’re not sure what is important. Aim to jot down the key ideas/issues with a few details and examples. Leave WHITE SPACE between ideas and terms so that you may add notes later.
Defintely add to your notes. Compare your notes with another student who takes good notes. Show your notes to your teacher to get feedback well before the test.
Remember, make your notes work for you! NOTES ARE GOOD IF they are REVIEWED and REVISED each week, preferably 2+ times a week. I recommend reviewing and recalling your notes the same day you take them, skip a day or so, and review and recall them again over the weekend.
