Free-Trial to Paid Conversion Drop

The problem

Management does not know how far trial-to-paid conversion has fallen, which learners and lead sources convert, or which of the recent changes is responsible. The Chief Executive Officer needs a data-backed funnel analysis of learners who signed up from 1 April to 30 September 2026 to decide where to spend marketing money, whether to rebuild the mentor team and what to do about the EMI partner.

How it works

1. Start the project — the 5-day timer begins and the workspace opens with every table loaded.
2. Solve 50 tasks in SQL or Python (30 basic, 15 intermediate, 5 hard). Each is checked instantly.
3. Write the final report in the workspace and add charts from your notebook.
4. Score = 70% tasks + 30% report review. 60 or more earns a certificate.

What you will deliver

• Answers to the 50 analysis tasks (30 basic, 15 intermediate, 5 hard), solved with SQL or Python in the JobPrax workspace.
• A final report written in the workspace for the Chief Executive Officer: executive summary, data quality, findings and recommendations.
• Two to four charts from your Python notebook, added to the report (for example the monthly funnel, conversion by source and EMI failures by month).
