I did 3 tests back to back but had to wait almost 2 hours as they didn’t have everything set up. Where I leave there are tests once a month so if I had failed I’d have waited another month… Then I realized it didn’t matter as couldn’t agree on days and time with a local training company…
Passed all 3 easily but make sure you have water or something to drink as I has a sore throat and staff had to help me with glass if water:)
