Hey Peacelilly,
Don't get disheartened honey. There are many Susan's members who only pop in at certain times of the week, so you might still end up getting some good responses. Just give it a bit of time.
As to advice, I can only advise what I would do in this sort of situation.
I say go for the tests, because ultimately they don't matter. IQ tests test logic and language and spacial reasoning - they do not give any indication as to an understanding of cause and effect/action and consequence. That's basically what your therapist wants you to prove, and the easiest way to do that is by being confident and mature in your responses.
I would be upfront with him and say that I would take the tests he requires, since I want my transition to be as simple and straightforward as possible, and conflict isn't part of that path, but that you will not be denied your will. There are other therapists, and while you realise that it might take you a while to locate a sympathetic one, eventually you will, given enough perseverance. Telling him all of this demonstrates maturity and determination, which are the qualities he would be looking for.
And I agree, it's bloody unfair that you're being made to jump through all these hoops, but ultimately the entire SOC, and IMO, the psychological profession, is about protecting the therapist more than the patient. There are however even alternatives there - many therapists use modified forms of the SOC altogether or else ditch them entirely and work on a case-by-case basis.
Good luck honey, and I hope this helps a wee bit.
