its because if you're interested in the subject, and the people who are teaching you doesn't give you the same hype, it might make you lose your interest and it might be boring unless you really like that subject and study it by yourself
but
if the people who teaches you know how to hype you up during class, you might take an interest to the subject that has been teached in class and might actually pay attention to it
but I don't really know its just from my perspective and opinions
