<p>i would try to pick my other classes first. then go to <a href="http://www.bu.edu/cas/writing/courses.html%5B/url%5D">http://www.bu.edu/cas/writing/courses.html</a> and visit the "schedule" link. scroll to the timeslots that your schedule still has free. and then from those, pick an interesting topic. and be sure to also check your professor's ratings on <a href="http://ratemyprofessors.com%5B/url%5D">http://ratemyprofessors.com</a> . they may not be the greatest, but try to avoid anyone who has lots of ratings below a 2.</p>
<p>if none of the classes are good enough, then adjust one of your other 3 classes and repeat the process.</p>
