Pitfalls to Avoid
Relying solely on drag-and-drop BI tools
Ignoring raw SQL queries and database architecture fundamentals.
Fix: Practice writing standard SQL queries and understanding relational structures.
Confusing statistical metrics
Mixing up mean, median, mode, and standard deviation interpretations in skewed data.
Fix: Review descriptive statistics formulas and outlier impacts thoroughly.
Overlooking data governance rules
Treating compliance, data masking, and privacy regulations as secondary topics.
Fix: Study GDPR, HIPAA, and data lifecycle management frameworks in detail.
Neglecting time management during mocks
Running out of time due to lack of pacing practice during full-length practice exams.
Fix: Rehearse timed mock exams under strict 90-minute conditions[cite: 8].
