What are my chances of getting into an Ivy League University

I am currently a junior in highschool with a 4.0 GPA and an AP college credit to my record. I have taken every honors cl available and am very involved in my highschool in community. Like being presidnet-elect of BETA, President of FBLA, Vice-President of Spanish Club, Student Council, Every Band Honor imaginable, Academic Team, Community Service at our city's courthouse, and I have a part-time job on top of everything. I made a 166 on my PSAT as a freshman and am taking it again this year, and have a 26 (awful) right now on my act, but am confident I can get it up to at least a 30 before graduation. I would like to know, how easy (haha, easy to get into an Ivy League) or difficult you would think it would be for me to get into an ivy league university (specifically Cornell) and go to an ivy league law school with financial aid and scholarships.
