Why are you speaking in the past tense, is your freshman year already over? You stated in another post that you were currently a freshman.
It will take a considerable amount of work to pull yourself out of the hole you dug yourself. You will need a 4.4-4.8 every semester until graduation in order to show your dedication. If academics isnt your forte then pile on the leadership and varsity sports, but go for competitive, physical sports like lacrosse, football, wrestling, hockey, basketball, swimming, and cross country.
