If Thaddeus knows two things very well, it's Columbia University and numbers. And the number two ranking wasn't sitting right with him.

Thaddeus wanted to understand what had driven Columbia's rise in the rankings. So he subscribed to US News and World Report to access the specific data Columbia had self-reported. For instance, Columbia claimed that 82.5% of its courses had fewer than 20 students, meaning a large majority of courses were seminar style.

Thaddeus found that the real number was far lower than the reported 82.5%. The correct figure was below 67%. As he kept crunching the numbers, more discrepancies emerged. Columbia had reported a student to faculty ratio of six to one, but Thaddeus' calculations suggested it was closer to 11 to one. Then came one of the most startling claims.

Columbia reported spending over $3 billion on instruction and teaching related expenses per year. That would mean, according to his calculations, that Columbia was spending more than $100,000 per student annually.
