How can I make my dad realize I can't get into the colleges he is convinced I can get into..?

^^exactly! When we was trying to find colleges for my hi stats; quirky kid who was graduating in 2006, we figured Chicago was then a “match” school -based on their acceptance rate of 40% in 2005. Then in 2007 [?] or sometime thereabouts, they decided to start accepting CA applications and …BOOM, the number of applicants sky-rocketed and their acceptance rate plummeted.
USC’s acceptance rate in 2005 was above 40%- that was his “safety” .
Its not anyone’s “safety” anymore. …
All because more students CAN NOW apply to more colleges , because of the Common App, with just a keyboard stroke.
