Work through them in order, or jump to the topic you need. 9 lessons include worked explanations and runnable examples.
Fundamentals
- What is Power BI & Business Intelligence — Power BI is a business analytics and data visualization tool by Microsoft that transforms raw data into actionable insights.
Data Preparation
- Connecting & Loading Data (Power Query Basics) — Power Query is the data transformation engine in Power BI that connects to diverse sources (Excel, SQL Server, APIs, web, cloud services) and cleans messy data.
Data Modeling
- Data Modeling & Relationships (Star Schema) — Data modeling is organizing tables and defining relationships so Power BI calculates metrics accurately.
Design
- Data Visualization Principles (Choosing the Right Chart) — A chart is only effective if it reveals the story in data quickly.
Dashboard Building
- Building Visuals & Dashboards — A visual in Power BI is built by dragging fields from your data model to the Values, Axis, Legend, and Filters areas.
DAX Formulas
- DAX Basics — Calculated Columns vs Measures — DAX (Data Analysis Expressions) is Power BI's formula language for creating calculated fields.
- DAX Common Functions (SUM, CALCULATE, FILTER, SUMX) — SUM() aggregates a column: SUM(Sales[Amount]) = total of all amounts.
Dashboards
- Interactivity — Slicers, Filters, Drill-Through — Interactivity turns static reports into exploration tools.
Deployment
- Publishing, Sharing & Refresh + Dashboard Project — Publishing moves a report from your desktop to Power BI Service (cloud), where users access it via browser or mobile app without installing Power BI Desktop.
Who this Power Bi course is for
School and college students in India starting from zero, and anyone revising Power Bi for placements, board practicals or a project. There is no prerequisite beyond being able to type — the first lessons assume no programming background at all.
How to study this course
- Read the lesson, then run the example in the built-in editor before moving on — reading code is not the same as writing it.
- Try the practice task at the end of each lesson. Getting it wrong and fixing it is where the learning happens.
- When you are stuck, ask the free AI Tutor to explain that specific line rather than skipping ahead.
