This course introduces the core concepts and algorithms of machine learning for making data-driven predictions. Students explore supervised learning techniques, including linear and logistic regression, decision trees, and basic clustering, using Python's scikit-learn library. Applications are directly relevant to Zambia, such as building models to predict customer churn for mobile networks, forecasting demand for ZESCO, or assessing credit risk for microfinance institutions. 25schools demystifies machine learning with intuitive explanations of algorithms, guided projects using Zambian datasets, and clear notes on model evaluation metrics, equipping students at Mulungushi University and CBU with the foundational knowledge to pass exams and begin applying predictive insights in the local Energy, Banking, and Retail sectors.

This hands-on course introduces Python, the industry-standard programming language for data analysis. Students learn core programming concepts (variables, loops, functions) and specialize in using libraries like Pandas for data manipulation, NumPy for numerical computing, and Matplotlib for basic visualization.

This hands-on course introduces Python, the industry-standard programming language for data analysis. Students learn core programming concepts (variables, loops, functions) and specialize in using libraries like Pandas for data manipulation, NumPy for numerical computing, and Matplotlib for basic visualization. The ability to automate data cleaning and analysis is a highly sought-after skill for Data Technicians, Business Intelligence Assistants, and Research Officers across Zambia's Banking, Energy, and Development sectors. 25schools supports this practical skill development with beginner-friendly coding tutorials, downloadable datasets from Zambian contexts (e.g., ZESCO consumption data), and debugging guides, ensuring students at UNZA and CBU can not only pass coding-based exams but also build a portfolio of relevant scripts for the local job market.

This course provides a comprehensive introduction to relational database design and the Structured Query Language (SQL) for efficient data extraction and manipulation. Students learn to create normalized databases, write complex queries involving joins, aggregations, and subqueries, and manage transactions. SQL proficiency is a fundamental requirement for Database Administrators, Data Analysts, …

This course provides a comprehensive introduction to relational database design and the Structured Query Language (SQL) for efficient data extraction and manipulation. Students learn to create normalized databases, write complex queries involving joins, aggregations, and subqueries, and manage transactions. SQL proficiency is a fundamental requirement for Database Administrators, Data Analysts, and IT Auditors across all industries in Zambia, including Finance, Telecom (Airtel, MTN), and Healthcare for managing patient or customer records. 25schools supports mastery with interactive SQL practice environments, a database of sample problems mimicking queries on Zambian business data, and cheat sheets for common syntax, providing students with the hands-on practice needed to succeed in both theoretical exams and technical interviews for high-demand jobs.
