That air brakes part is the toughest because, as you found out, the tests must be done in a certain way. I teach my students to keep this "seed" phrase in their mind:
OFF
You:
PUSH off the brakes
TURN off the engine
TURN on the ignition
That sets up the testing. Then just remember to set your foot in the brake pedal comfortably and don't move it at all till the one minute is over.
OFF OFF ON
One of my students actually taught me this helpful mnemonic: P-LABS.
(P)arking brakes - tug test tractor and trailer. (L)eak test, 1 minute. (A)larm, visual and audible. (B)utton pop test. (S)ervice brakes.

I don't know what it is... I know the material... I know how to do it, until the DMV tester gets in the truck...
I can describe how to do the in-cab, I can tell you industry standards... on it all and where my truck engages, I can do the external pre-trip, etc... I can drive really really good... shifting is smooth... lane control I got that nailed... backing into an ally golden, backing at all... I am good at... I have it all.. but I cannot seem to pass the in-cab once the DMV person gets in the truck.
Today, I forgot to shut off the truck during the leakage test... after I shut it off, put it in gear, and pushed in my brakes, I didn't redo the leakage test... this caused me to fail... everything else was spot on... but this is twice I have failed this dame leakage test... first time was because I moved my leg...
I dont know how to fix this... I know how.. and when the DMV person isn't in the truck... I can do it..
I am looking for advice on how to maybe fix this; I know it's nerves and pressure that cause me to freak out.

TWIC:
Transportation Worker Identification Credential
Truck drivers who regularly pick up from or deliver to the shipping ports will often be required to carry a TWIC card.
Your TWIC is a tamper-resistant biometric card which acts as both your identification in secure areas, as well as an indicator of you having passed the necessary security clearance. TWIC cards are valid for five years. The issuance of TWIC cards is overseen by the Transportation Security Administration and the Department of Homeland Security.
