I think I'm going to take it junior year right when school starts because I really don't want to take it more than once. That happened to me with the sat bio and it was really annoying because I had to re-study everything since by the time I took it the second time, I had already forgotten most of the material
As for the SAT I'm aiming for 2200+. However, I don't think I'm going to take the ACT as it's not that popular where I live.
@rose: What are the SAT averages for your school? Just curious b/c there's a lot of asian people at my school so scoring a 2300-2400 is not really a surprise. It really sucks though because I'm asian myself and I constantly feel the pressure of doing extremely well (on everything basically).
Oh and as for EC's:
FHS, NAHS, NHHS, NEHS
I plan to work at Kumon (tutor little kids ahaha) in the spring, and hopefully an internship at the local hospital over the summer. (keeping my fingers crossed lol)
