  35. Boo is right, and to the people saying things like don't cheat all I did was check answers. If you changed any answers then its still cheating dont judge the people that might need a bit extra help.and to the people saying change one answer so it looks like you didnt cheat thats a stupid thing to say because it brings your grade down if you do it enough and its ok to get it all right its an online school you'll be fine.
