ACT arrival time

Hi I was wondering if anyone knew if I have to arrive at 8am sharp as my ticket even though the test starts at 9am. Is it possible to arrive at 8:30 or so or would they not let me in?

Show up at whatever your printed ACT ticket says.

Why are you asking us, non ACT people, what time you should be at the test? Why risk getting the wrong information?

The ACT ticket specifically states the time. Or call ACT directly. Trust the source.
