Colleges love to see an upward trend. They understand that not every 14 year old has the maturity to place the necessary importance on grades; they love to see that immature 14 year old grow into a 17 year old with his priorities in place.
And don’t sweat the whole “good college” thing. There are thousands of good colleges in our country-- great places where student learn and live and grow. They say there’s a lid for every pot. Relax; you’ll find yours.
