Lupin because he was always kind to his students, and he always treated everyone well. He gave everyone a chance, and he had faith in all his students. When someone messed up, he didn't scorn them. No, he encouraged them to do better siguiente time.
McGonagall because she was so dedicated to her students, as well as to doing the right thing. ****POTTERMORE SPOILERS BEGIN HERE!!!!**** In her past, she experienced a lot of heartbreak and suffering. However, she didn't let those feelings get in the way of her teaching. And although she is strict, she always had faith in her students. She always seemed to hope they would succeed, even if she didn't always mostrar it outright. She stood up for her students, and she did whatever she could to help them succeed, and she really did care about them :)
I think it will be Professor Severus Snape becouse i would amor to study Potions (in school i where obsessed with chemistry) He is really a good teacher for thoose who like study his subject.
Dumbledore. Because in the book he is ALWAYS kind and patient.With everyone...even Voldemort.(in the beginning). In the words of Hagrid; "great man Dumbledore, great man!"
Professor Lupin.He's such a kind-hearted, understanding and helpful person that he makes a great teacher. Although it's quite tough to choose your favourite among Proffesors like Mcgonagall, Dumbledore,Flitwick and Sprout,I personally would refer to him as the best.
McGonagall. She may come across as a bit stern sometimes but she genuinely cares about her students. She does everyting she can to be there for them and protect them.
