5.学习期间可食的健康小食
尽可能地远离垃圾食品，才能保持高效的学习状态。相反，例如黑叶蔬菜、全谷物、花生酱、牛奶和海鲜一类的小食，可以助你实现高效学习。感觉疲惫？从长远来看，咖啡因或能量饮料似乎都无济于事。但是，你可以选择吃香蕉或苹果来补充能量。

6. Narrow it Down
If you try to study every single thing your teacher's ever said, you'll go crazy. Instead, focus on the most important topics. If you're not sure what those are, read the study guide (if there is one), or ask your classmates. Once you've nailed down the important stuff, if there's still time left before the test, you can move onto the finer details.

6.锁定重点
如果去研究老师所说的每项内容，那你肯定会疯掉。相反，你只需锁定最重要的内容。若无法确定这些内容，请阅读学习指南（如有）或询问同学。一旦锁定了复习重点，（如果测试之前还有时间，）便可进行更细致的复习。

7. Take a Break
Your brain can only take so much hard work at one time. For every hour that you study, take about 15 minutes to do something mindless, like taking a walk, listening to music or playing a computer game. (You can even take a 15-minute nap, if you're confident you can wake yourself up at the end of it.) It'll keep your stress level down and give your brain a chance to let all that information sinks in.
