I think that I have some advice. Don't try to mask your true self, that harms the process. If you are getting distracted by the noise of construction that's happening a block away just tell them. If you feel the need to violently shake your leg do that. It's not just the testing that you write down the answers to that make them understand what disability you have it is also the usually unnoticeable things like fidgeting, stimming, distractibility, echolalia, sensory sensitivity, atypical speech, and lack of fine motor skills. For example, they said that I have over developed my ability to announciate words to the point where I sound British, I can also be occasionally monotone.

it's hard via video call though I always bounce my leg and things like that they won't see or fidgeting etc. That worries me too. I want to hope I sound British not posh British but British considering I am British 😂 but thanks that's helpful
