As a 20-year-old with the attention span of a squirrel, it takes a truly phenomenal professor to hold my attention for 50 minutes, let alone an hour and 25. Cornell definitely has more than its fair share of life-changing teachers; I’ve had about one per year, and considering the implications of “life-changing,” I know I’m inordinately lucky. But it’s not just luck. I seek out — and successfully pinpoint — these professors with the help of a website called RateMyProfessor. Most students have heard of RateMyProfessor, but not many consider it a serious tool in the biannual quest for classes that fulfill requirements and don’t make one want to throw oneself down Libe Slope.
