You may also encounter questions related to class and sequence diagrams. My recommendation would be to: 1. Read the UML section thoroughly from Cade's book 2. Read important sections from UML Distilled - Fowler 3. If time permits, go through the UML book - by the three amigos. You will not require this level of detail for Part-1. Remember however that what you learn here is what you will use for Part-2. HTH.
