Not posting photos or the school name for obvious reasons, but the math team I coach qualified for State MathCounts and would have made AMC8 Distinguished Honor Roll if one student had taken it at school instead of at his leading center and I AM SO PROUD OF THEM ALL THEY WORKED SO HARD.

AMC8の2024年度過去問、好きなだけ(数日に渡って)時間を与えた結果、21問正解、2問うっかりミス、2問自分で解けずに解説を見る。という結果に。
自力でここまで解けるのは本当に凄い。ただし何しろゆっくりで注意力散漫なので、本番はうっかりミスに気を付けて進めよ～って感じかなぁ。
