Currently doing my GCSEs (qualification that we do in Britain at age 16) but I also take further maths which includes some basic calculus, lots of algebra, that sort of thing. I don't really know what the equivalent is in other school systems.
okay, I think we're around the same level then (not gonna be cocky, I could be wrong), but I'm also doing stuff that 16 year olds should be doing. Do you happen to be into engineering, I'm going towards that route.
