I could be wrong but, generally, I don't think it's a good idea for people to research these type of tests before they are administered. Otherwise, I imagine that this could influence the results.
For my diagnosis, there were a number of tests that I would have done much (much, much, much) better on, had I known what the test was and how it was administered. The example that comes to mind is the Wisconsin Card Sorting test (which assesses problems associated with the frontal lobe of the brain). Had I known how the test worked, I would have “aced” it. I went in not knowing anything and performed rather poorly on it.
