IBM Cognos 10 BI OLAP Developer: Frequently Asked Questions
The COG-635 exam leads to the IBM Certified Developer - Cognos BI OLAP Models certification from IBM. It is positioned at the Professional / Intermediate level. The exam validates the knowledge and skills expected of candidates preparing for IBM Cognos 10 BI OLAP Developer.

The COG-635 exam includes 60-65 questions and allows 90 minutes. Before test day, divide the available time by the number of questions in a timed practice set to establish a steady per-question pace. If a difficult item starts consuming too much time, mark it for review and move forward instead of losing momentum. A full timed practice session can help you decide when to move on, when to return, and how much buffer to reserve for a final check.
The passing score for COG-635 is 65%, and the official exam fee is $200 USD (approximate, varies by region). Because a retake requires paying the exam fee again, use timed practice results as a readiness check before scheduling your next attempt. If your performance remains inconsistent, continue reviewing weak domains and repeat a timed session before booking the exam.
