I applied (online), and my best advise is go in as if it is your worse day, and answer all the questions as if it were your worse day. Do not make the mistake of answering the questions as if it were an ok day. If some days you require a wheelchair, go in with a wheelchair, forget the makeup, etc. also, don't lie. just use info from worse days. I was approved within 6 wks. I hope that helps.
