check out the harvard board. I had read more than a few way before i made my account (but still remember them). Most recently they talk about him in the thread
Undergrad focus at Harvard. they say he teaches 5 classes and is out for the rest of the semester.
someone also cited this:
"Instructor: Students polled in the fall call Professor N. Gregory Mankiw
interesting (13%) and knowledgeable (15%). However, some assert that he is
boring (31%). They think his lectures are not valuable (19%) and complain that
he does not cover material outside of the book (23%). Students polled in the
spring say that he is knowledgeable (13%) but a poor (15%). Many bemoan his
boring lectures (34%), grumbling that they are no different from his textbook
(18%). 10% are disappointed that he only gives six lectures throughout the term."
The fact that only 10% are disappointed he gives so few lectures suggests something else about him too.
I know at Williams the professors do nearly all the grading, and certainly ALL the subjective grading. Is this true at yale?
