ALLAmericanGirl, I don't want to sound like an ass, but please stop giving out wrong information.
For starters, Notre Dame is not Ivy League. The Ivy League is comprised of Harvard, Yale, Princeton, Columbia, Dartmouth, Cornell, Brown and University of Pennsylvania.
Secondly, 99.9% of applicants do NOT go to community/junior college for two years before going to an Ivy League school... They go there straight after school. Sometimes they transfer out of community colleges, yes, but that is extremely rare. Most transfers come from other Liberal Arts four year colleges...
