Hi Ismail,
My viewpoint differs slightly.
UML Distilled is sufficient to pass the ibm tests 633 and 833.
But for exam 834, the objectives are very detailed and apart from what you have suggested, Craig Larman's book is very well written.
For all OMG certifications, just download the coverage map and it clearly states what topics you need to cover from the UML v2 specifications. This also can be downloaded from the OMG website.
The best way to go about this, I feel, is to first clear 833 and OMG foundation exam and then with time clear the 834 and OMG Intermediate exam. We can collate our efforts and resources, mail me at
