This review should be cumulative, covering briefly all the work done thus far in the semester. Practice self-recitation as a device for increasing memory. Organize your notes in a question and answer form and think in terms of questions and answers about the main ideas of the material as you review weekly. When preparing for exams, try to predict the questions the instructor may ask. Keep carefully organized notes on both lectures and assignments.
Good notes are one of the best ways for review.
Watch for key ideas in lectures and try to express them in your own words in your notes. Watch for headings and bold face type in your reading to give you clues of main ideas. Also, take down careful notes as to exactly what assignments are and when they are due. Be sure to schedule time for long term projects on the day they are assigned. For a lecture class, study as soon after the class as possible.
