There's a lot of confusion among candidates on the level of detail to go to in each diagram.
This is especially true for Component Diagrams. They are overly discussed (won't say hyped!!) in discussion forums.
Does you book guide how detailed component diagrams should be, should each JSP/ENTITY be represented in its own box or just the file names can be listed and what other details are expected by examiners in component diagrams. Similarly, sequence diagrams carry less marks with them but take a lot of time. How much detailed they should be? I hope book clarifies such confusions.
