MrsBW - I am a retired sw/tm mgr of a Fostering & Adoption team (30 years experience in all) and my advice is to stop worrying and trying to "second guess" what you might be asked. You must have noticed a lot of the replies are about specific issues related to their circumstances, and I imagine the same will be true for you.
The thing is you will be concentrating on these replies you've had and then find you are asked something completely different and will be "thrown" - it isn't meant to be a Q and A session but inevitably it will feel like that. As you know it is a multi disciplinary panel and before you go on, in the panel will decide who takes up a specific issue with you - it could be the medic (hence why someone was asked about a medical condition) or the education rep, or the child protection social worker, or the adopted person (panels are meant to have an adopted person on the panel but it isn't always possible.)
I think the one thing that is difficult for all applicants is to go into a room where there are 12 + strangers sitting around a table. They will all have their name and their job on pieces of card in front of them and they will all introduce themselves, but you won't remember who is who.
Panels know that applicants may be nervous (much better than being over confident) and make allowances for this. If you have a positive recommendation and the assessing sw has covered all the issues, there shouldn't be any problems. Take your time answering anything, and if you don't know what someone is "getting at" then say "sorry I'm not sure what you mean" because some panel members can confuse applicants in the way they ask questions/raise issues.
That's my advice for what it's worth............I'm not going to wish you luck, because being approved as an adopter is not a matter of luck, it is a matter of people like yourself applying to give a home to one (or 2) of the hundreds of children awaiting adoption, and a good assessor ensuring that they cover all the issues and the panel seeing you for what you are - a special person (NOT MsPerfect) as none of us are, but someone who has thought long and hard about adoption and been through quite a gruelling process and the panel approval is the final step in the approval process. The real hard work starts when the child/ren are placed.
