CODE FESTIVAL 予選について
• 3回あります
• 予選A : 9/24(土) 21:00 ~ 23:00(すでに終了)
• 上位100名(内 外国人10名)
• 予選B : 10/10(月・祝) 13:00 ~ 15:00
• 上位60名(内 外国人5名)
• 予選C : 10/23(日) 21:00 ~ 23:00
• 上位60名(内 外国人5名)
CODE FESTIVAL 予選について
一番デカい枠がもう終わっとるやんけ
心配いりません、予選Aを通過した人は予選
B・Cの上位各60名から除外とし重複でカウ
ントしないので、つよい人が抜けた中で上位
を取ればよく、逆に後半の予選の方が通過の
可能性は上がるとも言えます。

できんのか
CODE FESTIVAL 予選突破について
年々予選のレベルが上がってるって聞くけど
突破できるんか
うーん……、実はボーダー自体はそこまで上
がってないかも……?
CODE FESTIVAL 予選突破について
• 予選Aでの参加者(1問以上解いた人)の人数を比較
• 2014 : 497人
• 2015 : 788人
• 2016 : 794人(日本人のみ集計)
• あまり増えてない…?
• 実際、ボーダーも去年と同じくらいに思えた
CODE FESTIVAL 予選突破について
• 一昨年、昨年と比べて、問題の傾向が大きく変わった
• より「知識や経験が浅くても突破できるかもしれない予選」にし
ようという意思を感じる(効果が出ているかは別として)
• 運営側は初心者を求めているっぽい
• しっかりと練習を積めば、予選突破の可能性は十分ある!
