Filling out the PIP forms

Hi

We are only just getting around to completing the application form for pip for hf asd daughter... Basically didn't know anything about it until I started researching what help and support she might get if she went to uni. 

We have had a look at the questions and answered them, but it's there anyone who can help us review it to see if what we have written sounds correct or if it needs to be written a different way? 

Also how would I gather evidence? There's nothing I can show that I have to remind her to eat out wear appropriate clothes for the weather or that she didn't know how to plan a journey? 

Where can I get help?
