I'm still in high school.
At my old school, I was merely above average and heavily skewed towards one 'discipline', performing dismally in subjects unrelated to the humanities but claiming top spot for all four language 'sneak peek' classes and History. However, since quietly arriving at my current school in 2012 I've swept every academic ceremony, topping almost half or half of the subjects I do every year. I have also managed to get Dux of my grade every year I've been at this school, barely clinching it in 2012 but taking it by convincing margins in 2013-4. Thus, I'd say that, while there obviously are people better than me out there, I'm smarter than a good proportion of other high school students (I am, however, merely average at Maths).
