Remember, remember

Here we have an example that may seem like even more work than studying, but it is clever nonetheless. Sometimes when you study, you leave out parts of the class and textbooks that you think will not be on the test. And they might.

So what you can do is memorize the whole thing. You may think that it is a lot at first. But when you start doing it, you realize it is easier because you remember information progressively; it becomes easier to know what may come next.
