Learn, practise, explain

Try the exercise before reading its explanation. Answer the self-check questions in your own words, then compare your reasoning with the answers. Revisit any difficult section before moving on. No account or payment is needed.

  1. 01

    Spreadsheets: formulas, tables and trustworthy totals

    A spreadsheet becomes useful when each number has a meaning and each formula can be checked. Build a small event budget, follow a copied formula and discover why a missing value is different from zero.

    Learning outcome: Create a small calculation table, explain relative and absolute references, interpret an average correctly and sort records without separating related fields.

    Understanding AI and checking its work

    Learning outcome: Explain tokens and context at a beginner level, verify two types of AI error, write an effective practice prompt and protect privacy while preserving your own learning.

    Learning outcome: Identify direct and inferred personal information, explain cookies and private browsing, redesign an over-collecting form and review a file or photo before sharing.
