Students want to find the best way to put information into their long-term memories. They want to keep the information later when they take a test. What is the best way to learn information so they can remember it when they want to?
    When studying, you should read the whole lesson first. This gives you the whole picture in which to put the ideas. New information that fits into the whole picture is easier to remember than separate facts, You also learn faster if you look at headings, introductions, important words, summaries, conclusions, and anything else that helps to organize the material, which is easier to understand.
    Then the second step is to study the parts. Think about how they fit into the whole picture.
    If you have a lot to study, don’t try to do the whole job at once. Learning should be spread out and spaced. This gives the information time to "sink in." You should study grammar three times, a half hour each time. That is better than studying for an hour and a half at one time. Even shorter study periods are better for vocabulary lists and other difficult material. To learn the most in a two-hour study session, study different kinds of material; a half hour on grammar, 15 minutes on vocabulary, 20 minutes on writing, and so on. The change will help to keep you interested.
    You forget most quickly right after you read or hear something new. You should review right away so you won’t forget, and if possible, explain it to someone else. When you review and test yourself on the material, you are being active; active learning is better than just reading or listening.
