Six modules built around practical digital tasks.
Study one topic independently or combine several. Most modules contain three to five 35–60 minute practice sessions.
Spreadsheet foundations
Clean table structure, common formulas, sorting, filtering, references and basic error checks.
- Structured ranges
- SUM, AVERAGE and COUNT
- Relative and absolute references
- Basic validation
Reading data responsibly
Understand counts, percentages and rates before explaining patterns.
- Counts versus rates
- Percent change
- Time periods and denominators
- Careful interpretation
Data cleanup
Turn inconsistent records into a more reliable working table.
- Dates and formats
- Duplicates
- Missing values
- Category consistency
Visualization basics
Use charts to answer a specific question rather than decorate a report.
- Bar and column charts
- Time-series lines
- Part-to-whole views
- Titles and annotations
Digital workplace tools
Keep shared files and working information easier to follow.
- File naming
- Version awareness
- Comments and hand-offs
- Short process notes
Dashboard thinking
Move from a broad topic to a compact summary view with useful measures.
- Questions before metrics
- Simple summaries
- Filtering
- Limitations and context

Exercises resemble ordinary professional tasks.
Examples involve small datasets, shared records, weekly summaries and simple reporting questions. They are deliberately low-stakes and designed for learning rather than simulation of regulated or high-risk work.
