As a current student, congrats to all those who were admitted. A bit of advice for all of you: go to all the welcome weekends you possibly can. Especially if you're deciding between different schools, it is the easiest way to see if you fit in with the culture of a school. It only takes a few hundred bucks to ensure you make the right decision for the next 2 years.
For those of you who got waitlisted, quite a few of my classmates were waitlisted too, so don't give up hope. The whole process has taught me that B-school is a crap shoot. Some of my classmates who were waitlisted are the best students with top internships while some of the scholarship recipients are on the opposite side of things. That holds true for every B-school out there, so don't let a single waitlist or ding get you down.
Wherever you end up, work hard, get involved, and you'll end up far better off than the handful of people who still wish they'd gotten an extra few points on the GMAT or had been a little more charismatic in their Harvard interview.
