OP again; no worries about hijacking the thread. I'm very interested in what everyone has to say.

I guess looking at what each of the subcategories mean, I've largely experienced my discrepancies as being able to express myself well through writing but struggling to keep up in other aspects of performance. Going into tests I often feel that I know all the information but struggle to sort it out into what is and isn't important and get results that aren't indicative of the time I put into the material. I have a particularly hard time with specific details like dates and fields where I have to apply my knowledge (great at algebra because there's a procedure to follow, awful at geometry because proofs require application).

As for the point about reading, yes, I'd consider myself well read. However, I also gravitated toward reading early on because it came easily for me; I had large delays in other developmental areas such as speech. So I wouldn't be inclined to say that the differences are due to my reading but that my reading habits might have largely developed in response to my differences.
