Noooooo. IQ tests aren't really the kind of thing you can prep / study for, and even if you could somehow get materials, all you would do is invalidate the test results.

There's some good information about preparing for testing here: http://www.hoagiesgifted.org/test_prep.htm

You might want a more-comprehensive assessment than "just" an IQ test, which might give you more information about how a learning disability might impact test results. This page has more information, although I think it's not talking about exactly what I mean: http://www.hoagiesgifted.org/assessing_gifted.htm
