Coverage Map To prepare for examinations, candidates should refer to the Coverage Map. The coverage map shows the percentage of questions derived from a given section of the UML 2.0 specification for each examination level. The OMG specification can be downloaded from: http://www.omg.org/cgi-bin/doc?ptc/03-08-02
This doesn't stop you from learning UML 2 from a recenter version of the spec (or from a book). The newer versions have changed the numbering and locations of some subjects. You'll have to match the coverage plan and the spec contents yourself.
