A baseline day is a day you dedicate to completing a mock or simulation exam covering the entire scope of the BABOK® Guide v3. Ideally, you should build a baseline day into the start, the middle, and the end of your study plan. This way, you are able to assess where you are starting from (your baseline knowledge), determine how you are progressing with your knowledge and understanding (complete another mock exam in the middle of your study plan), and confirming you have a strong understanding and knowledge of the entire BABOK® Guide v3 by completing a mock or simulation exam at the end of the study plan. This study guide includes mock-style exam questions that you can use to help you establish your baseline at the different intervals of your study plan.
