Professor Vector was known among students as a "really strict" teacher, so much so that some pupils were unsure whether to take her classes. She was also known for giving her pupils plenty of highly complicated and difficult homework. Her subject was Hermione Granger's favourite subject while she was in school, but one of her roommates did not like it because she found it too difficult.
