2009 AIME 10+. If I can do that, then I'll be happy forever.
On a more serious note, the following scores would make me happy... well, not forever, but until next year at least.
AMC 10 150, AMC 12 136.5+, AIME 10+, USAMO 5+, USAMTS round 2 15+ (already submitted), USAMTS round 3 20+, USAMTS round 4 20+. Do reasonably well in Mathcounts too, I guess, but as long as I get to see Orlando I don't care.
Additionally, I must make red MOP next year.
