Dr. Lou is a young and sexy Organic Chemistry professor with passion in her field. Exams and quizes are no surprises and creative extra credit is earnable. She uses a rewarding teaching style, giving those that answer a class question first with bonus points, daily gratification of things you should know anyways, but just makes it fun to learn.

One of the worst science professors. She is unwilling to help during labs, she rambles about her personal life during lecture and then tries to crunch half the lecture during the last ten minutes. She doesn't explain the material well in lecture, reading the book made more sense than her lectures. Take her at your own risk.

I took Lou for both ochem classes and would definitely take her again if I would. She isnt the greatest when you ask her a question because she doesnt necessarily know a lot of ochem at all, but whatever she doesnt know she wont ask about.
