PIP application advice

Update: Just got a text saying from Independent Assessment Services saying I have a video assessment in two weeks! I had requested a paper assessment in my application form and am petrified about being able to attend convey(given my speech/jaw and associated problems) what I am being asked. On top of which the date is inconvenient as Ihave a hospital appointment at the time. I suppose I could request a change on that.
I am revisiting the guide but hyperventilating over attending now.
Any suggestions please? Also, has someone had a video assessment recently?

Thank you.

Thank you Gary. Did your brother-in-law have issues joining and they rang his telephone or did he have to get in touch to find out? Does the onus lie with IAS or applicant?

Do I request a change via the telephone contact or email or a letter? Just wondering about a mode that is safe and reliable?
Alternatively I could re-arrange the hospital appointment given how long I have had to wait to hear back from them.

Some of the assessment experiences that I read are very distressing and worrying. I explicitly requested a paper assessment in my application citing reasons for the choice. Could I write or phone them to re-request a paper assessment ? or might it be safer to just go with the option I am offered and endure the consequences?

All this has me worried and worsened my current flare as I am most apprehensive about not being able to adequately convey owing to my various difficulties and limitations including physical, cognitive and mental challenges including speech difficulties, brain fog and anxiety. Although I will have my friend who is my carer with me during this, I am really not upto this and specially for an entire hour. I had included very detailed responses in the PIP form hoping to cover maximum ground including a cover letter explaining my work situation. I hadn't mentioned anything about hobbies as I hardly have the resources to have any. I didn't think Audibooks and staring out of the window counts for much.
Although I will have a copy of the form and other evidence sent - I am unlikely to be able to look at, comphrehend and formulate a response and enunciate enough to make sense. Based on the guidance, I need to ensure that I volunteer information that may be relevant but not asked by the assessor. Being awful at multitasking and with braig fog, I am most likely to miss.

Sorry about the long post. Appreciate all your inputs and help.

Thank you Gary.

I rang the IAS helpline to change my assessment type where I was told I could change it to Paper but they would come back for an assessment anyway. I found that odd and asked if they had not seen my assessment request in Section 4, which is when I was told that IAS HP's don't even get the information we send in the PIP2 form! The lady on the phone said that they don't need any of the information supplied in the form for the assessment. Apparently they cannot list more than 6 medical conditions in their system, I have several more.

I thought the assement was to gauge how the disability affects the applicant, if the HP does not have an inkling of how or what, hasn't read the PIP form, how can the assessment be relevant?
This has come as a shock. Is it even true? Have I been misinformed? Has someone had a similar experience of an assessment with IAS?

I changed it to telephone for now but I am now more worried as to how I am meant to convey 38 pages worth of information with diagrams, pain charts plus more in less than an hour ? It is simply impossible even with the help of my carer.

Any experiences? Any advice would be much appreciated.

Thank you.
