Hi Mikalai Zaikin,
I prepared for this exam using Larman and UML Distilled.
I didn't read anything on UML 2.0. That was my mistake. Lots of questions on new syntaxes introduced on UML 2.0. I don't think I receive any questions on Timing Diagram.
Apart from this your exam simuators are good for practice. It would be better if you come up with a new simulator covering about UML 2.0.
If required I can also contribute to it.
For passing the exams I would suggest go through the syllabus and try to find out what happens in each steps mentioned in the exam syllabus.
DO NOT FORGET to download the DEMO for 833 and 844 from Pass4sure. DO NOT FORGET to go through again and again all the sample questions provided for 833 and 834. These sample questions you can download in the pdf format from the IBM certification site.
