Up to now, it's been about 10 yrs. living in america and im a junior and i am going to a college in korea after i graduate high school here. i was wondering if it's more easier for me to get in to like a global/international college since i lived here for 10 years? i did not so good freshman and sophomore year. my gpa was around 3.0-2.7 ish... is that way bad for college? do i need to get better grades??? i try but i just cant seem to get straight a's or b's
