when does showing interest in schools by signing in matter

A quick note about when you need to show interest in schools for consideration.

The ONLY schools you need to show interest in, which at the high school fair is by signing in, are LIMITED UNSCREENED schools. But, lots of schools will have you sign in anyway. I have no idea why. 

And head’s up, even schools that give preference to those who show interest, don’t necessarily do anything with lists signed at the fair. An article in DNAInfo last year talked about how often info those lists never went anywhere beyond sitting on a table at the fair. Some schools only considered school visits as showing interest. Wrong? Yes. But there’s no one out there overseeing all this.
