Looking for the most important information as you read helps you stay engaged with the material. This can help keep your mind from wandering as you read. As you find important details, mark them with a highlighter, or underline them. It can also be effective to jot notes along the edges of the text. Write on removable sticky notes if the book doesn’t belong to you. When you’re preparing for a test, begin your studies by reviewing your highlighted sections and the notes you wrote down.
