The person listening should ask plenty of questions. This activity may even give you insight about what questions I might ask of you. Put this wisdom to work for you. Rewrite your notes from class in a form that you can easily understand. When you do this, incorporate material and explanations from relevant sections of the text and any notes I provide you.
Writing is a good tool for organizing and synthesizing information.
When you are unclear and can not clarify things yourself, ask one of your classmates or me to help you. We may respond by asking you questions, but answering those questions will give you valuable practice for exams. Try to avoid cramming all night before the exam. This is usually counterproductive. Get a good night's sleep and come ready to think.
