I am trying to complete my PMP by end of  this month. Thanks to all people who posted about free tests. Please also check http://www.pmpden.com/free-sample-tests/. There are three small tests here. The second and third are better ones since they have explanations and can be accesed on mobile. The first is flash based and won't load on your iPhone / iPad. Keep posting new stuff and enjoy your project management journey.
