Has anyone used http://www.testtakeronline.com/catalog/pmp-certification-exam.htm . I took the free mock exam today and it seems to be really good. I am looking for a really good one because I have already taking Rita v7.0 three times and I am starting to get dup questions. I have also taken the 75 q's Oliver which is very good. Just wondering if I should drop $25 on testtaker or not. I am also looking through the notes one this site.
