chapman expects quite a bit from her students. although she's really demanding, her expectations are not at all unreasonable. in general chem, she holds an incredible number of office hours which are really very helpful. during my year of pchem, i gradually realized that once you have chapman figured out, it's really very easy to get an A in her classes. her tests are VERY similar to the problem sets. buying the book is never necessary in any of her courses. problem sets are a significant amount of work (especially in quantum-- oh my lord) but doable if you work with others and/or go to office hours. seriously, she's a really nice person and is willing to work very hard for her students as long as you work hard for her. also, the powerpoints: SO helpful. i barely took notes and instead just listened.
