Hi Augustus,
I hope your assessment goes well.
1 + 2 Yes, you should tell the assessor about anything you use in order to make your life easier.
3 I don't think we have seen many reports yet, I don't know what is being produced. You might remember that a 'score sheet' as such is not produced for ESA claimants, I don't know what the situation is with PIP.
