My D15 has a non-verbal learning disability. Last year her English teacher was going over a draft of a paper with her, and said, "How is that you can tell me all these great ideas and fluent sentences when we talk, but it doesn't come out in your paper?" This is a kid who scored 740 on SAT CR as a 13 year old... but it is torture to get her to write a paper. Handwriting is particularly difficult for her, so the laptop she got last year in school does help some.
