- Focus additional study on weaker areas
Performance in practice assessments can be used as a guide for further revision and preparation.
Hands-On Dashboard Exercises
Practical dashboard development is an important part of learning Power BI. Learners work on exercises that involve transforming raw data into meaningful reports and interactive dashboards.
Dashboard exercises may include:
- Sales performance analysis
- Financial reporting
- HR analytics
- Marketing performance analysis
- Inventory and operational reporting
These exercises help participants apply Power BI concepts in realistic business scenarios and develop practical report-building skills.
DAX Practice
Data Analysis Expressions (DAX) is an important part of Power BI for creating calculations, measures and analytical logic.
The training includes practical exercises covering areas such as:
- DAX fundamentals
- Calculated columns
- Measures
- Aggregation functions
- Logical functions
- Filter context
- CALCULATE and FILTER
- Time intelligence concepts
- Variables
- Advanced calculations
Regular DAX practice helps learners understand how calculations behave within Power BI reports and data models.
Power Query and Data Transformation
Power Query is used extensively for importing, cleaning and transforming data before analysis.
Learners practice working with:
- Connecting to different data sources
- Data cleaning
- Changing data types
- Removing errors and duplicates
- Filtering and sorting data
- Splitting and merging columns
- Append and Merge operations
- Creating transformation steps
- Preparing data for analysis
Hands-on Power Query exercises help learners understand how raw business data can be transformed into analysis-ready datasets.
Data Modelling Practice
A strong data model is essential for creating efficient and accurate Power BI reports.
The training covers practical data modelling concepts, including:
- Tables and relationships
- Primary and related tables
- Relationship cardinality
- Cross-filter direction
- Fact and dimension tables
- Star schema concepts
- Date tables
- Model organization
- Optimizing models for reporting
Learners practice building data models that support DAX calculations, visualizations and interactive reporting.
Build Practical Skills for Power BI Certification
The Power BI Certification & PL-300 preparation component is designed to combine exam-oriented learning with practical application. Instead of focusing only on theory, learners get opportunities to practice Power Query, data modelling, DAX, report development and dashboard creation using practical exercises.
By the end of the training, participants can build a stronger foundation in the key areas associated with the Microsoft Power BI Data Analyst (PL-300) certification and identify the topics they need to focus on before independently scheduling and taking the official certification examination.
Please note: Completion of a training program or mock tests does not guarantee passing the Microsoft PL-300 certification examination. The official exam is conducted and assessed independently by Microsoft.
