<p>I have seen the website (<a href="https://gs.columbia.edu/placement-tests">https://gs.columbia.edu/placement-tests</a>). But I am not sure when they are required and when not. I completed calc 1-3 at a different University so I shouldn't have to take any of the Math I or Math II tests correct? Is the Chemistry test required for everyone? I got a 4 on the Chinese AP test so does that qualify for the language exemption?</p>
<p>Thanks in advance.</p>
