As I see facebook status updates from my friends who are still in high school, I remember how stressful the first semester of senior year can be when it comes to choosing what schools to apply to.
I'm now a freshman here at Harvard and I'd be happy to answer any of your questions about the school life - classes, extracurriculars, the environment, the social scene, the most challenging parts of the application process...
College Confidential was a HUGE resource for me last year and I'll try to help you out like students did for me last year. In particular, I am an international student and I did early action, so if you're in either half of that situation my experience might be particularly relevant.
Finally, I started a blog since I got to college - I mostly use it to keep in touch with my family, but I realized it might also be a useful resource for prospective students:

Feel free to ask me questions either by commenting on my blog of by posting on this thread!
