I’ve tried to pass Cognos BI Modeler exam this weekend and failed. That leaves me rather disappointed and anxious for another try.
Some notes and comparison with EP certification:
- BI Modeler is way faster (~110 questions in 2,5 hours vs ~135 in 3,5 for EP)
- BI Modeler is problem oriented (most questions consider sql\modeling problems, rather than product specific problems) and cognos-terminology dependent (reporting traps names and descriptions should be memorized by heart)
- BI Modeler has higher pass mark (84% vs 73% for EP). I scored 75% and would pass if score was as for EP. )
- EP test includes lots of rather meaningless questions directly addressing some minor issues, which are depicted only in documentation and rarely accessed in practice (like publishing restrictions and format precedence), and no modeling questions at all
- BI Modeler includes some “best-practice” questions where answer is quite unclear (maybe explained in trainings, though)
As a conclusion: Modeler is much-much harder than EP test. Even regarding mine 4 years of EP experience vs 2 years of BI, I can be quite clear in this — it’s harder.
Yet a goal to achieve.
