ChemWOOT Testimonials

Since 2005, students preparing for the major high school Olympiads for math and science have chosen AoPS Online’s WOOT programs.

By having different presenters teach different topics, you all capture the beautiful diversity of chemistry and optimize the expertise with which it is revealed. When a student asks a question, we have a panel of world-class experts ready to contribute--and argue about--an explanation. [...] This class has been simply fantastic.

I really love this class. It opened a whole new door for me in the chemistry field and increased my eagerness to study further into the general area of chemistry. It is easy enough to keep me from instantly giving up, but difficult enough to be challenging, and rewarding!
