CHEM 115
Quality 3/5Difficulty 5/5
This class is bloody difficult unless you actually like chemistry. Weisshaar is an unbelievably nice guy, but he teaches like an upper 300/400 level class, and he expects us to understand the content instantaneously - you'll need to get to know your TA very well. If you survive his class, everything other class feels like a breeze! 50% scale to A
