Is more testing worth it? (GRE's)

<p>Hi, I'm a college senior who was diagnosed with a learning disability 2 years ago. I receive extra time on tests at my school, but apparently more testing is required to receive extra time on the GRE's. How fast do you have to be on the GRE's. I was fine on the SAT's, but the ACT's tore me to pieces because they just went too fast. I want to get the testing but it seems so expensive. It's $200 for a one hour pre-testing consultation alone which just seems exorbitant. </p>

<p>Also, if I do get the testing, I'd be tested for aspergers as well. I believe I have it, but I've never been formally diagnosed. What are the advantages of a diagnosis?</p>
