What do colleges look for in an essay?

<p>I am writing my college essay on how I finished my senior year of high school early by taking classes at community college. I think that it is definitely a different and unique essay, and I think it stands out.
Is this a good topic? And how long should essays usually be?</p>

<p>500-700 words. Are you a transfer student?</p>

<p>Yes, I will be applying as a transfer. But I have less than 24 college level credits, so I want to write an essay because I did not do very well in high school and on my SAT scores, but I am good at writing, as it is my strongest area, so I think that writing an essay will help.</p>
