<p>the only problem i see is that most exams tend to be formulaic, and so students learn more about taking the test than learning the material. But then, it is up to the teacher to make the class a true college class through supplementary assessment, such as projects, research and labs. But if you are asking if they are extensive enough, then yes. Have you seen the art history curriculum!? Or the Computer Science ab exam? It’s huge. I think they are comprehensive enough.</p>
