Configure financials and Perform Business Central operations together account for roughly 50-60% of exam items. This reflects the consultant's day-to-day focus on financial setup and operational execution. Set up Business Central and Configure sales and purchasing are also critical but tend to appear slightly less frequently. Allocate study time proportionally, but ensure you have solid coverage across all four domains.
In practice, Set up Business Central establishes the foundation; Configure financials and Configure sales and purchasing build the operational structure; and Perform Business Central operations executes daily tasks within that structure. For example, you might set up a company, configure a chart of accounts and posting groups, define customer pricing, and then process a sales order. Understanding these dependencies helps you answer scenario questions and troubleshoot issues on the job.
Hands-on experience significantly improves both exam performance and job readiness. Prioritize labs that cover company setup, general ledger configuration, and sales order processing, as these appear frequently on the exam. If you have access to a sandbox environment, spend time creating a customer, setting up a posting group, and posting a sales transaction. Even 10-15 hours of guided hands-on work can bridge gaps that study materials alone may not fill.
Many candidates overlook the importance of posting groups and how they control account assignments, a frequent source of errors in scenario questions. Others rush through setup questions without considering the downstream impact on reporting and compliance. Additionally, confusing the order of configuration steps (e.g., setting up customers before defining posting groups) can lead to incorrect answers. Slow down on scenario items, re-read the business requirement, and trace the configuration path mentally before selecting an answer.
In your final week, focus on weak topic areas identified in practice tests rather than re-reading all materials. Run a full-length timed practice test to validate pacing and pinpoint remaining gaps. Review the explanations for every incorrect answer, not just the correct ones. On exam day, arrive early, read each question carefully, and flag items for review if you're uncertain, you can return to them after completing easier questions.
