I've taken a government honors course in another school system (I relocate frequently), but the school I attend now wouldn't let me take AP Gov without taking another course beforehand. My hole-riddled math education is the primary reason calculus is scary, with "brightness" a close tie. Scored dismal marks in algebra I/II and geometry, but aced pre-calculus and analytic geometry...I don't know how well that bodes but 'tis what it is. What are you majoring in, if I may? I've heard Calc II is horrendous but required for certain paths.
I don't really know what extracurriculars exist; cross-country running, book club, NHS, NEHS are all I really know of. Once school starts - I moved here mid-March - I will inquire about them.
