Learning to ride a bike is a good analogy for learning to take standardized tests. There are not many manuals on how to ride a bike. Balance, steering with handlebars, and pedaling in a coordinated manner are primarily learned through experience. Learning a new coordination of thinking and behaving on an SAT or ACT is similar. Both require experience and practice to find balance.
For standardized tests, there is also curriculum to consider, and the process can be far more complex than learning to ride a bike. Student efforts in English and math at school do not always translate well to these tests, but when dialogue is mixed with practice on standardized test problems, a new thinking and behavior can be shaped while a student performs and finds his or her way to mastery (akin to one holding onto the back of a bike seat until another starts to ride on his or her own).
