Be nice. And tell your therapist to be nice, or at least, professional. It's entirely possible that your mom has undiagnosed bipolar - there is a strong hereditary component, and some of her behaviors that you've described in the past suggest it.
My older one took the SATs under a program like that when she was in 6th or 7th grade. I don't remember much coming of it beyond a lot of junk mail, but it's been 20 years, and I'm sure it looked good at the time.
