I think the way that it is/can be consideed hazing is if you tell a group of people that on this day and this time you have to meet here and study.
But that just made me think of something that will probably start far more than I expect.
But if that is "hazing" then are lab hours and idscussion sections for class "hazing"? because I know discussion groups that a teacher reqiure you to go to at a specific time, and place seem like the same thing.
Just wanted to play devil's advocate for a minute there
