<p>The answer is:</p>
<p>It depends. If you were happier at your first school, you need to figure out the reasons why it was/is better than the top-15 school you currently attend. Once you figure that out, it will be easier to find other colleges/universities to transfer to.</p>
<p>I assume you're new to the top-15 school, based on your post, so I'll add a note of caution: it may take a little while (a semester or two) to get into the swing of things, so keep an open mind. </p>
<p>I'm not sure if your drive to Stanford, Harvard, etc...is motivated by your not liking your top-15 school, as you stated that you think your first (top-20) school was better for you. Again, I say this because you feel like you got bad results when you applied as a first-year while still in HS.</p>
<p>If the school you're at currently shares similar characteristics with those transfer schools that you're interested in, aiming for the top-10 may place you in the same predicament. Also, transfering a second time may not look very good to grad school adcoms. It might appear like your drive to transfer is motivated by rankings, rather than by fit, major, etc...</p>
<p>You don't want grad schools to even momentarily entertain that idea. At best, it makes you appear indecisive. At worst, it makes you look like you have difficulty making tuff decisions, and are guided by what others think (i.e. USN). </p>
<p>I'm not saying that is the case, but be careful. You may inadvertantly compound the situation, if you are seeking more prestige in a transfer school rather than one that fits (top-10 school or not). See how the term goes before doing something drastic.</p>
<p>Just a word of caution.</p>
<p>:)</p>
<p>PS--It may be hard to give the school you're at a chance, when you have a "wandering eye" or are on the lookout for something better.</p>
