Even if I don't need to, I still do sometimes. Just not much. So pretty much, if you don't know something, you ask the teacher first? My parents don't trust me at all, especially not with schoolwork. I'm not sure why, since I get it all done eventually, but they always ask and come see what I'm doing. Well, at least you got to re-take it with help from the book. I had an open book test once, but it was still pretty hard, since you had to discern stuff and come up with conclusions that the book didn't exactly say.
