Change in Schedule: Worth Notifying?

<p>Quick question that I wanted some CC members to weigh in on:</p>

<p>My Spanish 6 class couldn't fit into my schedule this semester, so I am taking Differential Equations instead, and I also added Ethnic Literature instead of an aide period. These changes were made after the mid-year reports were submitted to colleges. Is it worth it / necessary to notify the colleges to which I have applied?</p>
