<p>No, I do not think this will hurt you.
Matt McGann (MIT) gave an info session in my area and said, "MIT is looking for mostly A's in mostly hard classes."
Plus, adcoms look for grade trends, so they're going to see that maybe freshman year was slightly "low" (and it's really not all that low, really!) but after 9th grade you really kicked it into high gear and achieved. So, good job!</p>
