To the two who have interviews coming up on the 21st-- first off, congratulations! I hope you enjoy your interview day; Chatham does a pretty good job of making you feel welcome. 🙂 If you have any specifics about the interview date, please feel free to PM me.
Also, if it makes you feel better, they do shoot for a class size of 36, however they actually accept around 70 or 80 students... I just found this out at the open house when I volunteered this fall (I'm a 1st year student) because I guess that many people will get accepted and eventually turn Chatham down for a different school... So although they will have around 20 "accepted" from priority, they do "over-accept" so that's why being on the waitlist isn't so bad... The chances of you getting in are still decent. 🙂
As far as the essays, they are not difficult. One will be some type of morals/ethic scenario where you'll be asked "what would you do" and then the other 2 that I had were more about me as a person- talk about a trait that you feel is a good one that you would bring to the group if you were accepted and talk about a time when you faced a difficult situation and how you overcame it and succeeded.
So, again, congratulations, try to breathe and if you have any questions I am more than happy to help! 🙂
