<p>what are they? i was on ratemyprofessor.com, reading up on all my profs and i came across OWLs (although it makes me feel sort of harry potter-ish 
haha) and clicker points.</p>
<p>OWL is the Online Web Learning homework that the Chem department uses. Tedious, but it really helps.
Clicker points (assuming you have Williamson) are just questions/pop quizzes/attendance stuff that she does during her lecture that are part of your grade. Something like 14 points total out of 700 (not really much).</p>
