How similar are these practice tests to the real deal?

Yeah, When I did the airbrakes the first time it asked about ABS, which in the book always refer to checking the sides of the tractor or trailer for symbol or looking underneath for the ABS wires off the brakes but the answer at SOS(DMV) was look at the dashboard for ABS symbol. They gave me a few curveballs that screwed me up the first time, but today I smashed it in like 3 min, the lady was like "you're done already?" lol still gonna hit the book some more as I wait to meet with the school Monday.

Also I had to get my MVR and I forgot I have a 5 over and fail to yield from 2010, is this gonna hurt my chances at getting a job now? I remember what they were from, one guy wouldn't let me over so I had to gun it to get around him(#######) and the fail to yield was from me pulling out of a place and the building creates a blind spot so you can't see traffic to the left of you(was turning right) and this stupid cop was flying down the road for no reason and was just mad I pulled out and he almost hit me because he was driving too fast. Of course it was all my fault though It was late at night and no traffic, in the winter and he was driving to #### fast for road conditions!
