Where can I find help (suggested readings, mock exams, links, etc.) in preparing for the IBM certification test OOA&D in UML (test 486)?

IBM provides suggested readings, a practice exam, and other reasources – see http://www-4.ibm.com/software/ad/certify/edu486c.html. Also, check out the OOA&D and Patterns sections of my Object-Oriented Bibliography at http://www.softmoore.com/OOBibliography.html.
