<p>“Everyone is happy at Dartmouth” just is not true. I have a friend who went there and was NOT happy. She had gotten a large scholarship (assisted by a family friend in the application process) from an external source. She did not want to let the friend down, so went on and completed her degree at Dartmouth. But she did not have a great experience, partly because her passions were not among those that were strengths at Dartmouth. It was quite a few years ago, so the details are pretty irrelevant. But that blanket statement really isn’t true… the OP is right to be asking those questions. I personally think the OP has excellent self-awareness for a high school senior, and is doing the right thing to follow up. OP, you might ask the admissions office to link you up with an art major, and maybe also help you find a fellow Buddhist to email with to answer your specific questions. </p>
<p>I would say that the introvert question is very difficult for any extrovert to answer… extroverts really don’t understand the context or what “pressure” actually feels like to introverts. So finding an accurate answer to that question might be hard. Not sure the admissions office would be able to find you an introvert to chat with. 
Of course, all admissions people ARE extroverts, they probably wouldn’t even see the point…</p>
