I completed the AA form totally by myself two and a half years ago. Was told by one of my AC to remember to reply to questions as it applies on my WORST days, not as on other times when things are a little better.
Much to my astonishment I received the Higher Level AA - and it has been so much help. With this, I have been able to purchase so much assistance. From my lovely mobility scooter, to taxis when required. I think I will have to re-apply in a few months time. I did not keep any copy of what I wrote last time, but will just complete any new form honestly and tell it how it is on my bad days and nights.
I have been told that physical problems (such as I have), are so much easier when these forms are being assessed, rather than mental ones.
Attendance Allowance has made a big difference to my life, the extra money did pay for my gardner (when I was in my house),and my lovely electric bed , my trolley which I use around the flat, amongst other things. I used some of it (back in the past) - to pay for first class train journeys which gave me much more comfort on long journeys, etc.
Can only say that AA has enabled me to continue leading a totally independent life. Wonderful.
