Study tips
Exam Format Understanding
- Expect 5-7 Performance-Based Questions (PBQs) at the beginning - skip them initially and come back after answering multiple choice
- PBQs may involve drag-and-drop scenarios, matching visualizations to data, or selecting appropriate statistical methods
- 90 questions in 90 minutes means roughly 1 minute per question - manage your time carefully
- You can flag questions for review - use this feature liberally
- The passing score of 675/900 means you need approximately 75% correct
SQL and Data Mining Mastery
- Practice writing SQL queries daily - JOINs, GROUP BY, HAVING, and subqueries appear frequently
- Understand the difference between INNER, LEFT, RIGHT, and OUTER JOINs with practical examples
- Know when to use WHERE vs HAVING clauses
- Memorize common aggregate functions: COUNT, SUM, AVG, MIN, MAX
- Practice identifying data quality issues in sample datasets
Statistical Concepts Focus
- Memorize key formulas: mean, median, mode, standard deviation, variance
- Understand when to use each measure of central tendency (mean vs median vs mode)
- Know the difference between correlation and causation - this is commonly tested
- Understand hypothesis testing basics: null hypothesis, alternative hypothesis, p-values, Type I and Type II errors
- Practice interpreting confidence intervals and statistical significance
Visualization Selection
- Create a chart matching different visualization types to their best use cases
- Bar charts for categorical comparisons, line charts for trends over time, scatter plots for correlations
- Understand when heat maps, treemaps, and bubble charts are appropriate
- Know dashboard design principles: F-pattern reading, 5-second rule, appropriate use of color
- Practice identifying misleading visualizations (truncated axes, inappropriate chart types)
Hands-On Practice
- Don't just read - practice with real tools (Excel, Tableau Public, Power BI, SQL databases)
- Download sample datasets from Kaggle and practice the entire analysis workflow
- Create your own visualizations and dashboards - hands-on experience solidifies concepts
- Practice data cleansing techniques on messy datasets
- Use free SQL sandboxes to run queries daily
Governance and Compliance
- Understand data roles: data owner, data steward, data custodian - know who's responsible for what
- Memorize data quality dimensions: accuracy, completeness, consistency, timeliness, validity, uniqueness
- Know basic GDPR principles: right to be forgotten, data minimization, purpose limitation
- Understand data classification levels and appropriate security controls
- Study master data management concepts and their business value
Practice Exam Strategy
- Take at least 3-4 full-length practice exams under timed conditions
- Review every incorrect answer - understand why you got it wrong and what the correct reasoning is
- Track your scores by domain to identify weak areas requiring additional study
- Simulate exam conditions: no distractions, timed, full 90 questions in one sitting
- Use practice exams to build stamina - 90 minutes of focused testing is mentally demanding
Exam day checklist
- Arrive 15 minutes early for in-person exams or start your online check-in process 30 minutes early
- Bring two forms of ID for in-person testing; ensure your testing space is clean for online proctoring
- Skip the PBQs (Performance-Based Questions) initially - answer all multiple choice first, then return to PBQs
- Read each question carefully - CompTIA often uses 'BEST' or 'MOST appropriate' phrasing
- Eliminate obviously wrong answers first, then choose between remaining options
- Watch for scenario-based questions that require applying concepts to business situations
- Flag questions you're unsure about for review - you can return to them before submitting
- Don't overthink questions - your first instinct is often correct unless you spot an obvious error
- Manage time: Check the clock every 20 questions to ensure you're on pace (roughly 30 minutes per 30 questions)
- Use all available time - review flagged questions and verify your PBQ answers before submitting
- For calculation questions, write down given values on your whiteboard/scratch paper to avoid errors
- Take a deep breath before starting - confidence from preparation will carry you through
- Remember that visualizations in questions may be intentionally misleading - analyze them critically
