<p>Has anyone taken it with Mr. Wu? Any inputs? How hard/easy is the class? How’s the professor? Can’t find a review on him on ratemyprof.</p>
<p>Thanks!</p>
<p>You shouldn’t refer to a professor as “Mr.” </p>
<p>“Professor Wu” would be the correct way to refer to him or address him.</p>
<p>He appears to be a visiting professor, that is why you can’t find info on him.</p>
