The IBM Cognos 10 Controller Developer (exam code C2020-605) is the exam you pass to earn the IBM Certified Developer - Cognos 10 Controller certification, a credential at the Developer level. It is also connected with related credentials such as IBM Cognos Business Intelligence. If you are mapping out a certification path with IBM, this exam is a milestone worth planning around.

The C2020-605 exam includes 91 - 94 questions, and you have 90 - 120 to complete them. With that many questions on the clock, pacing is part of the challenge: divide your time into rough blocks as you go, and flag the items that stall you so you can circle back at the end instead of burning minutes on a single question. A week or two before your exam date, sit at least one full timed session in the 2Pass4sure test engine under the same time limit, so the pace feels familiar rather than frantic on the day.

You need 70% - 75% to pass the C2020-605 exam, and the official registration fee is 200 USD. That fee is due again in full for every retake, which makes thorough preparation the cheaper investment by far. Before you book your seat, test yourself with the 2Pass4sure practice questions until you are scoring comfortably above the passing mark on a consistent basis — it is the simplest way to avoid paying for the same exam twice.
