<p>Does it make a difference where to you take ACT? I need to register and I have choice between two locations: local HS or local university.</p>
<p>Either choice is just fine. You can take the test wherever you like. Choose the one where you will be most comfortable. You are likely to know more fellow test takers at the local HS and may be more familiar with parking and logistics.</p>
<p>The more familiar environment the better. For my D, I register her for her HS. She could even put her cell phone in her locker while taking the test.</p>
