<p>you're right about grades and SSAT score. Most applicants have straight A's and incredible board scores, so neither of them will get you into prep school (however, terrible grades or board scores can raise a red flag in the admissions committee so don't sleep on them).</p>
<p>What you need to get across in your application: strong character and personal qualities. At this point in one's academic careers, it's a little early to distinguish oneself at the national level (there is no USAMO or RSI for middle schoolers, for example), so admissions officers tend to look for committment, disipline, and overall, passion in your academic and extra-curricular activities. Show them what you love most in your life, and how you could channel that passion to make something great out of it at Andover. </p>
<p>Essentially, you want to portray yourself as interested and interesting. First and foremost, Andover is an academic institution so you would want to show how you love learning. Disipline and drive are also biggies: Andover wants students who will take something from the school and also give back to it. There are too many lazy geniuses out there for one to try and get by on intelligence alone. Hard work is essential and you need to be able to show them you have the drive to succeed at Andover and in the world. </p>
<p>Atmosphere: competitive, but not overtly. I came originally from Fairfax County, and the feeder school to TJHSST, so the students there were competitive to the extreme; comparing test scores constantly and showing off board scores to each other. None of that happens at Andover, but you can tell everyone wants to out-do each other. It's a question of whether or not you prefer subtly or bluntness in how your peers compete with you.</p>
<p>The workload is manageable but you have to work at it considerably. Organization becomes an art, but once you master it you prepare yourself for so many things in school, and in life afterwords. </p>
<p>Most students who leave Andover, do not do so by choice. Some are expelled for various actions (the most prevalent being plagarism and drug use), and some leave for other extenuating circumstances (one girl had a chronic sleeping disorder so she left because she simply could not function). I actually haven't heard of anyone transferring out of Andover to another prep school, although the opposite certaintly happens (albeit uncommonly). </p>
<p>I have to run now, but I'll get to your last question shortly. Hope that helped!</p>
