When I was a student and teachers would say, "Study for your math test!" I would think, "How do I 'study' for a math test?" I now realize that 'study' is the wrong verb. You really need to 'practice' for a math test.
Math tests not only require you to KNOW material, they require you to know HOW TO DO something with that material. This shift requires a shift in your preparation. Unlike other tests, there is no way to prepare for a math test the night before. At that point, you either know the material or you don't, but there is no faking.
Have you ever heard the phrase, "It's all about who you know"? Every adult could probably tell you about some opportunity that arose because they knew the right person at the right time.
As human beings, relationships influence everything we do! Why do you think golf is such an integrated part of the business world? Because golf gives business-people the opportunity to build trust and develop relationships that are vital for successful business deals. This same principle applies in school, too.
