Even though in Britain, the snow was falling, Hagrid had to admit that Kongo was hot and rainy. He was grateful that he was able to repeat his OWLs and had managed to pass his OWLs in DADA, charms, transfiguration, potions, herbology, astronomy, healing and care of magical creatures. Hagrid was able to take his NEWTs in these subjects in summer. He was grateful that the expulsion was lifted and he was able to finish his education, but now he had to focus for the NEWTs in those subjects apart from healing.
