If you are used to referring to the BABOK^® Guide v3 as your reference guide at work, then you will be familiar with the terminology, structure, and overall content coverage of the guide. This will reduce the time you need to prepare for the exams. However, if you are brand new to the BABOK^® Guide v3, you will need to allow time to get familiar with the structure, terminology, and general content. This will inevitably have an effect on the amount of study time you would need to plan for.
