How does the USACO Promotion system work?

Could anyone explain to me how the USACO Promotion system works?


Described on

If we don’t ICP a USACO contest, when will the cutoff score come out if we want to know whether we got promoted or not?

:sweat: Sorry, I guess I didn’t look hard enough :V

Typically within a week? It varies (sometimes a lot) from contest to contest
