Yeah, pretty much.
And it's just an ACS...you've had one of those before, yes? It's all MC, 4 options (1-2 clearly wrong, 1-2 to trip you if you don't know the concept well, and the correct 1)
If you've been doing pretty well in the course so far and feel like you 'get it', at least mostly, then you'll be fine on the ACS. If you haven't been doing well/don't get it, then there's not really anything you can do at the 11th hour. Standardized testing is standardized. Which means you should hit around your class average on the ACS. And scoring for the ACS is percentile based (and those %iles are from 20 years of administering the same exam), so you don't have to get everything right to get a good score. So...don't stress about it.
