It is really important" Minnie Driver studying organic chemistry at an outdoor Café in Cambridge while being distracted by Matt Damon. 3 4 "It is important I learn this. It is really important" "Do you have a photographic memory?" Organic Chemistry is not a course of memorization! Organic Chemistry is a course of ideas. To do well in CHE 321 you must be able to solve problems! All students are allowed to bring a personal information card to the exams. "It is important I learn this. It is really important" "Do you have a photographic memory?" Minnie Driver studying organic chemistry at an outdoor Café in Cambridge while being distracted by Matt Damon. 5 6 1 9/5/2008 "It is important I learn this. It is really important" "Do you have a photographic memory?" "It is so much fun studying organic chemistry! Are you mad? Have you completely lost your mind? Nobody studies organic chemistry for fun." "It is not useful, it is not a necessity." Minnie Driver studying organic chemistry at an outdoor Café in Cambridge while being distracted by Matt Damon. 7 Life, at its most basic level, involves molecules and their transformations. Organic Chemistry is a study of molecules and their transformations. Our knowledge of life at the molecular level is very limited. "It is not useful, it is not a necessity." Minnie Driver studying organic chemistry at an outdoor Café in Cambridge while being distracted by Matt Damon. 8 "It is for someone like you who divides their evening time between batting cages and bars." "It's for someone like you who divides their time between batting cages and bars." Organic Chemistry requires problem solving. If you are successful in Organic Chemistry you will become more skilled at solving complex problems. Problem solving is an important life skill. "It is not useful, it is not a necessity." Minnie Driver studying organic chemistry at an outdoor Café in Cambridge while being distracted by Matt Damon. 9 "It is important I learn this.

"It is for someone like you who divides their evening time between batting cages and bars." "There are some very smart people at Harvard and even they 1 have to study because this is really hard." 0 What is the secret of Organic Chemistry?
