School: Stanford
Required prelims (we call it comprehensive exams): Micro, Macro, Econometrics
When taken: First attempt: end-of-May til early June. A comp for every Friday. Six hours each. 100% fun guaranteed.
Retakes: Everyone gets a second attempt at the end of September (before the 2nd year starts); up to about four or five years ago you could take as many metrics comps as you want (need), then they made it four attempts overall, our year is the first one when we'll have two attempts in metrics. Micro and Macro were always two attempts.
Score required to pass: I think for Macro and Micro it's about two thirds of the points. For metrics one third (and it's the one with the largest number of fails). It's not quite clear what makes the cut - whether it's absolute or relative. Most of the class ends up with very close scores, even though some above the threshold and some below.
