There are several types of study guides for several different subjects, but in the end the point is the same: They help.

Many people lose focus while practicing for an exam or doing their homework, but a study guide forces them to pay attention to what they are doing and what they should be reviewing rather than memorizing something that will never be brought up in class.

Study guides are also great for those who learn through repetition. The guide sys exactly what they need to know and they can read it as many times as they would like without worry that they misunderstanding the information.

Often study guides, when given by a teacher, have both the questions and the answers that will later be on the test. It is basically cheating without the guilt, which is a pretty gosh darn great.

Study guides are essentially one of the best tools any student could possibly have. Without them, they have to focus and study much harder than necessary and most likely will not absorb as much information. If you want to pass that exam, use a study guide.
