Received the bundle of documents from DWP for tribunal

Hi, I am my daughter’s advocate. She has had PIP for the last. 16 years for her autism, dyspraxia, ocd, add and anxiety. In January it was removed. We applied for a mandatory reconsideration which was turned down and are now heading for a tribunal. We have received their bundle of documents and i want some ideas on how to approach them to make points for the tribunal. I look forward to hearing from anyone.
Thank you.
