Wait-Time app. There's a good chance that the centers will not be crowded this early in the semester. But as the end of the semester approaches, it can get very crowded. So you might want to go ahead and get some practice in using the wait-time app. You have an entire week to take your test. And you can do it anytime that the center is open. But some times are less crowded than others. And you especially want to avoid going to the center near closing time, because even a short wait might mean that the center will close before your time allotted for the test expires. So plan ahead and pick a good time by avoiding "peak use" times.
