Hi, Answer only the questions asked....dont go off on a tangent
look the judge in the eye when you talk to him/her
if you are in pain and need to alternate standing with sitting, dont be afraid to ask if you can stand up
take a few seconds before you answer every question to think about what you are going to say. if you do that for every question, if you are unsure what to say it doesnt look like you are making up an answer if you hesitate

dont minimize what the limitations to your life are that are caused by your illness, medications etc. can only stand so long, sit so long, walk so far etc.

being nervous is ok, most people are

if you dont understand a question ask for a clarification

bring whatever prescriptions you have with you in case the judge wants to look at them

good luck tomorrow
