You can download a free ETS test at gmac.com, but as far as I know, the results you get there are not realistic. I think it's better to practice with ETS tests, Kaplan books are also good in the math part. Anyway, I don't think it's a good idea to prepare for the test alone, especially for the English part.
Good luck!
