Now people are really going to want to help you.
On the topic of "stupid" things, not using the search feature might qualify as one. Like I said, there are popular and extensive threads about such things. Nobody was trying to make you look stupid. We're just pointing something out because people on here are quick to assume that 22+ is the "norm" or something; it freaks people out and is without reason.
Also, with the average being a 19 (really closer to a 20--I'd be surprised if it doesn't make the full jump after this cycle), that means that a slew of people are accepted with lower scores. Don't think that SDN is an accurate representation. We're a very small portion of the applicant pool.
Edit: Here is one to start you off.

I know there are also tons of threads with more individualized stories out there.
If you see someone post in a thread like this that they had a 19 or below and applied, check their post history and view their more recent posts. They might talk about their interview experiences and where they were accepted (or rejected).
