ご指摘ありがとうございます。ご指摘は正当でした。実際の出題形式と照らして確認したところ、正解が最も長い選択肢になる問題が大半で、本番に多い「適当でないものを選ぶ」形式や計算問題が不足していました。本日、全問を本番の出題形式に合わせて見直し、計算・数値問題40問を追加した内容を配信しました。アプリを起動すると自動で反映されます(アプリの更新は不要です)。ご購入代金の返金は App Store の「問題を報告」（reportaproblem.apple.com）から申請いただけます。改善のご要望はお問い合わせフォーム（https://www.nano-invitation.com/contact）からもお寄せください。
