<p>They aren't difficult. I took them for french and math, and well, I didn't fail them.</p>
<p>no, you will not find out your roommate at orientation.</p>
<p>last year, the housing department sent out housing assignments and roommate assignments in late june / early july. you'll find out by an email and by checking the "residence assignment" link on the BU student link (<a href="http://bu.edu/studentlink%5B/url%5D">http://bu.edu/studentlink</a>). but if youre going to a relatively late orientation, youll be able to talk to your roommate online before then and maybe find out if he's going to the same orientation. fun stuff.</p>
<p>some schools require placement exams. i know COM requires a foreign language placement test proctored AT orientation and CAS requires a foreign language placement test taken at home before orientation. there's also a math test and an engineering test, which i know nothing about. for instructions, use <a href="http://www.bu.edu/orientation/orientation/student/exams.html%5B/url%5D">http://www.bu.edu/orientation/orientation/student/exams.html</a></p>
