When you click on your upcoming appointment, it should show you the details. If I remember correctly, the information to test your system will also be present there.
You can also run a system check by going to

Please be advised that Pearson Vue is undergoing routine maintenance on Saturday, 21 November 5:00 p.m.- Sunday, 22 November 3:00 a.m. CDT. During this time, you may not be able to schedule, reschedule or cancel test appointments. I don't know if system checks will be available.
If you are taking the test this calendar year, you shouldn't have to spend much time with Agile.
Good luck with your upcoming test!
