Exam specifics
The IBM Cognos TM1 Developer (Test COG-310) certification exam (as of this writing) follows the same format as most IBM certification exams. The following information describes the test itself in more detail.
Length
As of this writing, the certification exam contains a total of 63 questions.
Format
As of this writing, the certification exam is multiple choice and is given electronically.
(Note: it is not currently accessible via the internet. The candidates appearing for the test must schedule an appointment to take the exam at a certified test facility).
Maximum time allowed
As of this writing, the allowed time for the certification exam allows for a total of 90 (consecutive) minutes.
Once the exam is started, time expends and does not stop until you indicate that you are done with the exam (or the total time allowed is exhausted). Once you begin the exam, if you must take a break, keep in mind that the break does not stop or pause the clock, so be prepared to complete all questions on the exam at a single sitting.
As in a written exam, you have the ability to skip or page forward and back during the time allowed.
There is no advantage for taking less time to complete the exam. Therefore, it is advised that you take the time to go back and check over the questions and answers which you finish early. This will also allow you to make sure that you answered all of the exam questions.
Questions that you do not provide an answer for are marked incorrect and will affect your total score. So, do not leave any unanswered questions! Make an educated guess if you have to!

- Identify variables, their types, and how they are used
- Identify when to enable cube logging in a TI process
- Describe when to store values versus accumulate values when loading data
- Identify how to maintain objects created through TurboIntegrator
- Describe how to troubleshoot TI processes
- Aside from TI, describe various ways to load data into TM1 cubes
- Rules (25 percent)
- Describe the advantages of using Rules versus using TurboIntegrator
- Determine the target area of a rule
- Identify the significance of order in rules
- Describe the use of the DB function in rules

- Identify a lookup cube and how it might be used
- Describe common uses of lookup cubes
- Time considerations (3 percent)
- Identify ways to structure time dimensions
- Data presentation and reporting (3 percent)
- Identify techniques for presenting data in a TM1 application
Minimal score required to pass
