Get job-ready as a junior data scientist
The route to a junior data scientist role. Build the analyst's foundations (statistics, SQL and Python), then learn to build, test and explain machine learning models on realistic Nigerian business data, and to use them responsibly. Data science jobs ask for more than models: they ask for clean data, honest evaluation and results a business can act on, which is what this track teaches.
