There are many ways to ensure you are writing good annotations. One way to do this is by focusing on the important aspects of the text. Don’t waste time trying annotate parts of the text that have little meaning or don’t support the main Idea of the text very well. Make notes of words you find confusing or don’t understand as this will help you think to go look them up later. Lastly summarize what you’ve read at the end of each section, this will help you to retain what you have read as well as making it easier to go back in the reading.
