Harry’s 3rd year seemed to be the hardest because of Sirius black, dementor’s and his Quditch.Quditch was a game played by wizards and witches flying on a broom to catch a golden ball to win the game. Quditch was ruff, because it was Harry’s captain, Oliver wood’s last year at hogwarts and he wanted to win the cup. They eventually did end up winning the cup, but Harry had to learn to fight of the dementor after they attacked him at his first match. After the quditch matches and exams Harry finally came face to face with Sirius black, and learned that black was an innocent man .
