3.做好全部准备
也就是说，准备好你的学习资料。开始学习之前，确保所有的书、笔记、学习指南和书写工具摆在桌上。不给自己起身和翻找的借口。

4. Turn Your Notes into Flash Cards
Now that you've got all your notes in front of you, open up a pack of index cards. As you read through the important facts, rewrite them in Q&A form on the cards. For instance: to study historical facts, write the historical fact on one side of the card and the key details on the other side. To study geometry formulas, right the name of the formula on one side and the formula itself on the other side.

4.把笔记转为记忆卡
现在，把所有笔记摆在面前，然后打开一包索引卡。将浏览到重要内容，以问答形式将抄写在卡片上。例如，要学习历史事件，可以在卡的一面写上历史事实，在另一面写出关键细节。要学习几何公式，可以在卡的一面写上公式名称，在另一面写上公式内容。

5. Snack Healthy While You Study
If you want to stay sharp while you study, stay away from junk food. Instead, snack on studying-friendly foods like dark leafy greens, whole grains, peanut butter, milk and seafood. Feeling sluggish? Caffeine or energy drinks won't help you in the long run. Get your energy boost instead by eating a banana or an apple.
