No proof to support it, aside my current [Completed] tag. I beat XII after a long, long comeback of over 3 months... Only to be excellently proud about it. I might retry XII just for laughs and get a souvenir picture... After all, why not?
If you think Course X is hard, it REALLY IS hard. I had the most problems in VIII, IX, X and XII. VI was piece of cake, as well as VII, where most players had problems in.
