As one of the authors of the exam I can tell you to concentrate on the new features of MSP 2010. You can use just about any of the reference books but you should know hold to use the software more than where a button is located. For example – what view would you use to see something or what table. Know the features of both the pro and standard version. Project Server is not mentioned on the test. Also look at the Microsoft site to find the objectives for the test and make sure you understand all of those topics. You might also feel more comfortable by taking a substantial (not button pushing) class.
