L0

Know the role

  1. Read a role through its responsibilitiesRequired

    Translate a role description into three observable learning goals.

L1

Build foundations

  1. Spreadsheet formulas and reconciliationRequired

    Build a sourced calculation table with an independent check.

  2. Statistics, samples and uncertaintyOptional

    Describe a distribution and its limits of inference.

  3. Variables, conditions and loopsRequired

    Independently: Write a small numeric summary program that handles empty input.

  4. Data structures and complexityRequired

    Independently: Compare lists and dictionaries for lookup tasks.

L2

Develop core skills

  1. Git and collaborationRequired

    Independently: Practise changes, diff review, commits and branches.

  2. Debugging and reproductionRequired

    Independently: Describe input, expected/actual result and reproduction steps for a bug.

  3. Testing and edge casesRequired

    Independently: Design normal, empty, boundary and invalid-input tests.

L3

Practise scenarios

  1. Research, citation and argumentRequired

    Write a sourced analytical paragraph with limitations.

  2. Interfaces and error handlingRequired

    Independently: Define inputs, outputs and failures for one function or API.

  3. Small project and READMEOptional

    Independently: Build a small tool with setup, tests and limitations.

L4

Build a work sample

  1. Present an inspectable work sampleRequired

    Submit a work sample with method, results and reflection.

Try a practice set

Calculations and choices receive immediate checks. Review open responses yourself against the rubric. All examples are educational.

1. What is the sum obtained by iterating over [2, 3, 5]?
2. Which test belongs with a fix for dividing by list length?
3. After the interfaces and error handling task, state one assumption, one supporting fact and one condition that would change your conclusion.

Small tool README and test log

For this small tool readme and test log, bound the problem to one educational scenario. List inputs and assumptions, preserve calculations and distinguish findings from missing evidence.

Define the question, scope and success criteria of this small tool readme and test log.

Record data, source links, dates, units and assumptions.

Write reproducible steps with calculations, evidence or a process map.

Separate observations, interpretation and recommendations.

List unknowns, validation steps and conditions that change the conclusion.
