currenthly, doing high school/college/secondary school, or whatever you can compare it to in your local system
for the dutch, i'm in fourth grade Gymnasium.
FYI, Gymnasium is the heaviest education you can get at this age, it includes Latin, and the way i picked my subjects physics, chemistry, general sciences, biology, history, and lot's of other "fun" stuff.
for the future, there are a few ways i might go, always something wiith physics and chemistry, perhaps a hint of biology. then, i might go for research, i might go teaching, or i might do something as a journalist, the last seems my favourite option.
i would NEVER oick anything like SysOp as a job, computers are a fun hobby, but i'd go mad if i would be forced to use them 24/7.
