Shifting in a turn?

So here's my situation. After hours and hours of worrying almost to the point of making myself sick, I took my DOT tests yesterday. I passed pre-trip and backing (the one I was really worried about), but failed the driving part due to multiple small things that I forgot. Here is my question. At SAGE, they have instructed me NOT to shift when in a turn until my trailer is even with the tractor. The tester from WYDOT told me one of the reasons I didnt pass was because I didn't get up to speed while in my turn. He said "I wanna see more giddy-up and go in the turns, you need to get up to speed." Sitting at the intersection, I would start out in third gear, shift to fourth before entering the intersection, and ride 4th until the trailer was even with the tractor, then go up through the gears. That's how I had been instructed at SAGE to do this. So I'm not sure whose right, SAGE or WYDOT. I just want to know the correct procedure, so that I pass the driving test next time.

 

Right, that's what SAGE was telling me. Then WYDOT said that I needed to use my gears and get up to speed in the turns.

 

I rode 4th gear until my trailer was even with the tractor, then went up through the gears. I made sure both were completely in the lane, then shifted from 4th. I'm just trying to figure out where I went wrong so that I don't do it again. The other things I did wrong on my test, I knew were wrong right after I did them. Such as, I forgot to use 4-ways at a train crossing (non-hazmat), and during an emergency stop, the left corner of my trailer stuck out in the road 6 inches. Those things I knew was wrong after I did them. I also guess I have a bad habit when driving a manual, that I drive with one hand on the wheel, one hand on the gearshift. I also missed an overpass height sign. Those are all simple "slap on the hands, dont do it again" things I can fix, but the turn thing still has me confused.

 

First, I asked the Director at our SAGE, and she agreed with the WYDOT tester. I asked the instructors at SAGE and they said that WYDOT wanted us NOT to shift until the trailer was even with the tractor. I have been looking this morning in my Wyoming CDL manual to see if I can find out what it says.
