Read the PSI North Dakota candidate information bulletin first, then drill national concepts such as contracts, agency, financing, and fair housing under timed conditions that respect the 150-minute national limit. Block separate study time for NDREC trust account rules, broker supervision requirements, Recovery Fund statutes, and licensee advertising duties referenced in the state outline. If you pass one portion and fail the other, North Dakota rules allow you to retake only the failed portion within twelve months of your first examination without repeating the portion you already passed. When you want interactive reps on Casa Academy today, open the free practice path using the embedded practice diagnostic. Those items help you practice pacing and review explanations, but they do not replace North Dakota statute study or PSI outline review.
