<p>I dropped orchestra for my 2nd semester and took astronomy instead. On the original common app I indicated that I would take orchestra since that was 3 months ago. Do I need to tell Caltech this? They should know from the mid year report right?</p>
<p>hmm i have the same question. I recently found out I won't be able to take one of hte college classes I signed up for due to timing conflicts. I listed this class on my application.</p>
<p>Just send the admissions office an email.</p>
