Can i still get into harvard or a ivy league school?

School just ended and i will be a junior next year in high school. The majority of my freshman year and a semester this year, i failed most of my core classes (gpa 1.2 as of november 2010). It wasn't the fact that i was incapable of achieving good grades, there was just alot of things that contributed as to why my grades were so low (family, environment, my music career). Long story short, I as able able to resolve these conflicts and manage to get straight a's this quarter. Hypothetically, i can prob recuperate my gpa up to a 3.2-3.8 by next year if i take all aps and do well. I wanna try to get into Harvard, one of my teachers said if all this works out i have good chance because i can use my academic history to my advantage and im pretty confident i can get a nearly perfect, if not perfect score on the sat. Is there any truth in this? Any recommendations? Thanks
