Stand by testing

I was just wondering how likely it is that one will actually be admitted in the test center and actually take the test when standing by. Has anyone here taken the ACT or SAT standing by? If so, did you get sent home due to lack of space, or did everything go smoothly?
- I registered for the act a couple of weeks ago, and to my surprise, all three of my choices were full. So, I was assigned to a deserted school in the surburbs of pennsylvania. I really don't know the area and it seems like the school has a certain dress code to. My original choice were perfect since I am from New jersey and they were close to my home, in philadelphia. So, I might have to stand by at these test centers after all.</p>

<p>Any comments would be helpful.</p>

<p>PS. Last year, I registered for the sat one day before the deadline and still got assigned to my first choice test center.</p>

<p>I just noticed the large number of typos in the original post --sorry about that.</p>

<p>I would call and let the test center know and ask them what you need to to do...
Also make sure you have all the registration stuff.
I wanted to standby test, but I didn't have the right registration form, so I wasn't able to do it.
It seems like schools will always have some extra room for you.</p>

<p>I took it standing by, easily. It might vary by region, though, so call the test center.</p>

<p>Ilovebrown, was the test center full when you took it standing?
And did eanyone here hvave trouble with standing by to take the tes?</p>

<p>Yeah, when I tried to sign up online, they said it was full, so we called them and they explained how standby works. I'm not sure how I got in, but I was admitted as soon as I showed up.</p>

<p>So, can someone else relate personal experiences with standby testing?</p>
