<p>People make it to ISEF based on their regional science fairs. Only a limited amount from each fair can go. Based on where you live, this can be either very competitive or not at all. If you live in North Dakota, you probably won’t have much trouble qualifying. Long Islanders, though, may have a harder time. My regional fair was pretty competitive, so I didn’t qualify. (I was kind of an alternate…) I would say overall, based on where CCers live, it’s pretty hard to qualify, and it’s a significant accomplishment just to be able to go there.</p>
<p>Happysunnyshine, it looks like you will have a very productive summer whether you get in or not. I sincerely hope you get in, but clearly you show the initiative to succeed no matter what.</p>
