Common mistakes include focusing only on a diagnosis, minimising difficulties, or giving vague answers without real examples. Explain how you manage each relevant activity on most days, including whether you can do it safely, to an acceptable standard, repeatedly and in a reasonable time. Mention help you need, prompting or supervision, fluctuating symptoms, and what happens on better and worse days rather than saying simply that you can manage. If the assessment report seems inaccurate, check the official GOV.UK guidance and consider seeking advice before requesting a mandatory reconsideration.
