In 2023, we had 13 students who are qualified to take the AIME (American Invitational Mathematics Exam) either through the AMC 10A/12A or AMC 10B/12B. 4 students among them also qualified to USAMO or USAJMO. 7 students who took the F=MA (Physics Competition) and 1 student advanced to take the USAPhO exam. Please join us to congratulate them all!Solution 1. Connect segment PO, and name the interaction of PO and the circle as point M. Since PB and PD are tangent to the circle, it's easy to see that M is the midpoint of arc BD. ∠ BOA = 1/2 arc AB + 1/2 arc CE. Since AC // DE, arc AD = arc CE, thus, ∠ BOA = 1/2 arc AB + 1/2 arc AD = 1/2 arc BD = arc BM = ∠ BOM.The Mathematical Olympiad Program (abbreviated MOP) is a 3-week intensive problem solving camp held at the Carnegie Mellon University to help high school students prepare for math olympiads, especially the International Mathematical Olympiad.

Problem. Given a sequence of real numbers, a move consists of choosing two terms and replacing each with their arithmetic mean. Show that there exists a sequence of distinct real numbers such that after one initial move is applied to the sequence -- no matter what move -- there is always a way to continue with a finite sequence of moves so as to obtain in the end a constant sequence.
