Standby ACT, should i go to a small town or a big city?

<p>Im going to drive from Mexico to the USA so i have two options for the ACT.</p>

<p>Where do i have more chance of getting a test place, in a city with 1-2 million people and atleast 3 test centers or in a small town with less than 100,000 ppl were the only test center is the local high school. The big city im considering is Tucson and specially the test center in the University of Arizona.</p>

<p>I missed the deadline for a few hours, feels so bad, i either take my ACT now or every and each of my college applications gets destroyed.</p>

<p>One interesting thing: i took the SAT II last month in a test center here in Mexico and I was the only kid taking it, however they sent a package of 7 test/booklets, that means 6 more kids could have taken the test stand-by mode. Does anyone know how what kind of packages does ACT send to the test centers?</p>
