At some point during your academic journey, you encountered at least one instructor who gave you a pop quiz. Even if they forewarned you at the beginning of the school year that there would be pop quizzes, they never told you exactly when the pop quizzes would happen. The point was for you as the student, to always be ready and to have an answer with enough knowledge about the subject matter that on any given day, you can pass a test. In this life, we know that things are going to pop up and test what we know, we just don’t know exactly when, so we have to be ready at all times. Don’t be surprised when the tests pop up. You knew you would be tested.
