Well if you're talking about stats then yes all of your stats can go up to level 100 and above I think for skills. My Redguard has a level 105 conjuration skill he's a master in that and 90 something in sneak. But when it's time to level up and you sleep then a page comes up which might have Strength,speed ect. those can only go up to level 100, I know because my character strength is at level 100 along with encomburance(sp?)
