Just wanted to thanks everyone for the help and actively participating in this forum. This helped me a lot to get my SCEA certificate. Here is the score I see in cert database.
Grade: P Score: 87 Comment: This report shows the total points that could have been awarded in each section and the actual amount of points you were awarded. This information is provided in order to give you feedback on your relative strengths on a section basis. The maximum number of points you could have received is 100, minimum to pass is 70. Class Diagram (44 maximum) .......................... 38 Component Diagram (44 maximum) ...................... 39 Sequence/Collaboration Diagrams (12 maximum) ........ 10
In brief main points I kept in mind while working on solution is Class diagram: 20-22 classes. extended BOM. Shown variables and few methods. Technology independent. Component diagrams: 20-30 components. Used most of the design patterns here. Seq diagram: one for each usecase. Diagrams were clear and I tried to avoid unnecessary details such as did not display any screen names. Tool Used: Netbean 6.1. I think it is improved a lot now. but still slow.
