Wanderers, I literally just had the exact same experience (well, almost...day one, after waiting for 3 hours, their computers went down, day two, there computers went down for about 2 more hours, all said I was there for 7 hours today) at the same location you were at, but I guess I didn't argue loud enough about the air brake test. Thus walked away with failed second test. No-one there would listen to me when I tried to tell them it was wrong. They even brought in a DPS officer which was of no use to me. Can any of you PLEASE PLEASE PLEASE tell me where you got the info for proper test, as I cannot find it anywhere on TX.GOV sights regarding the "CVO knowledge test" to show the nitwits at the test center, as they don't seem to want to take my word for it. Now I'm just a little mad that I folded too quickly. Thank you. and congrats for getting through to these folks.
