<p>The nice thing about the quarter system is that it lets you have your cake and eat it too. Let’s say you are enjoying a particular course and prof., and want to continue studying the subject with that prof. the following quarter. You can usually continue to do so by taking the next course in that sequence with that prof. the following quarter. If, on the other hand, you would prefer to try something (and/or someone) else, that option is typically also open to you.</p>
