Begin with programming and data handling, then statistics and evaluation before more complex models. Progress depends on practice and prior knowledge rather than a fixed job timeline.
Before you begin
Choose a real learning or work question, then use fictional examples if you plan to share the exercise publicly.
Work through the idea
Treat the example as a planning exercise rather than a prediction about every employer or learner. Write down your goal, relevant constraints and the evidence you have. Choose a next step you can review and revise. Keep training, project work and verified professional experience distinct in any public description.
- Build Python and SQL foundations
- Complete a reproducible analysis
- Add a validated predictive experiment
Practice task
Design a learning plan with one demonstrable deliverable per stage.
Check your result
Each stage has an entry requirement and a check that shows independent understanding.
A mistake to avoid
Do not collect tools without learning how to frame and evaluate a question.
Keep a review note
Save the inputs or scenario, your reasoning and the result you checked. Explain one assumption and one case that needs more work. Revise the exercise after feedback and distinguish what you demonstrated from what remains untested.
