how do credit hours factor in to an application?

<p>Hey guys, I am a freshman at UNC and considering transferring elsewhere (looking at Stanford, UCB, Columbia or Harvard). I took 13 credit hours my first semester and got three A's and one A-. I am again taking 13 credit hours and with any luck will get four A's. Do my stats look totally unimpressive given that I am not maxing out my credit hours? Also, I am planning on studying abroad this summer for another 6 graded credit hours, rounding out the year with 32. Any feedback is appreciated! Thanks.</p>
