When is the deadline for making my class as Pass/Fail?

<p>When is the deadline? and where should I do it? Is it possible if I do it online? Thank you very much :)</p>

<p>Sept. 10 is the deadline. Not sure how it is done. Have you gone online to see if you can do it that way?</p>

<p>What subjects are excluded from p/f?</p>
