How to Study Smarter, Not Harder

Here are some of our favorite tips that will help any student study smarter, not harder：

Recite As You Study

Reciting?saying things out loud—should first take place as you read through each paragraph or section.Test yourself.This will help you to understand as well as learn faster because it is more active than reading or listening.It will also help you to notice your mistakes and the topics you have trouble understanding.

Study the Middle

The best time to review is soon after you've learned something.You are more likely to remember the material at the beginning and the end of the lesson, so make sure you focus on the middle when you review.

Take Fuller Notes

Notes should be in your own words, brief and clear.They should be tidy and easy to read.Writing notes will help you better than just underlining as you read, since it forces you to re?write ideas in your own words.

Sleep on it

Study before going to bed, unless you are very tired.It's easier to remember material you've just learned after sleeping than after an equal period of daytime activity, because your brain continues to think even after you've fallen asleep.

Combing Memory and Understanding

There are two ways to remember：by memorizing and by understanding.Multiplication tables, telephone numbers, and math formulas are better learned by rote(死記硬背)while ideas are best learned by understanding.

The more ways you have to think about an idea, the more meaning it will have：the more meaningful the learning, the better you can remember it.Pay attention to similarities in ideas and concepts and then try to understand how they fit in with thing you already know.Never be satisfied with anything less than a completely clear understanding of what you are reading.If you are not able to follow the thought, go back to the place where you first got confused and try again.
