<p>"while those taking non-TO classes can’t take the second writing course until junior year. "
This is NOT correct. See the following information about the writing requirement- taken from the USC Catalog
[USC</a> Catalogue: The Schools: USC College of Letters, Arts and Sciences: The Writing Program](<a href=“http://www.usc.edu/dept/publications/cat2009/schools/college/writ.html]USC”>http://www.usc.edu/dept/publications/cat2009/schools/college/writ.html)
“Students usually enroll in WRIT 340 in the junior year, and may not take the course earlier than their sophomore year.”</p>
