I don't even know who he is. What was he ranked? That's just how marks are moderated. Well assuming he was first, that just means the highest mark in the class must have been 97 or 98 (which is crazy).
Raw mark cut-off? I can't really say. It would depend on the exam. But close to 90, maybe 88ish? Btw this is just what I think. Our first place got 89 so we got kind of capped but I got 80 flat, SDD was my lowest mark.
