Hi
I have found this makes a great difference. My DS did poorly his freshman and sophomore year. Got better in Junior and most likely strait A in Senior year. But still he finished Junior year with a 3.2 GPA. Not competitive for the academy. So starting end of sophomore year he took college classes. Two were on campus and five were on line. He did a total of 18 units and got a GPA of 3.95. Bingo....according to the academy he was competitive and has been recommended for an appointment. Now this is just grades and not all the other stuff he has done including being a nationally ranked athlete. But I can truthfully say that for my DS, the extra college GPA made it possible.
Regards
John
