OOP Mini Project in Python: Complete System Design & Implementation (OCR A Level Computer Science H446)

Move students from isolated OOP exercises to building a complete system. This ready-to-use bundle guides them through a whole mini project: analysing a problem, designing classes, writing and testing the code, and evaluating the result. It brings together everything from your OOP sequence and mirrors the stages of the A Level programming project.

Please note: this is a practice project to build skills ahead of the OCR H446 programming project (NEA). It is not an NEA task and should not be submitted as coursework.

What’s included

PowerPoint presentation: a stage-by-stage walkthrough of the project, with worked examples and class diagrams
Project brief and student tasks: a clear scenario, requirements and structured steps, with scaffolding for weaker students and extension for stronger ones
Hands-on build activity: students design and code a multi-class system, such as a library, shop, booking or game system
Testing and evaluation tasks: test plans, test data and an evaluation against the requirements
Full mark scheme: model solutions, a marking guide and examples of what good looks like

Topics covered

Analysing a problem and writing clear requirements
Identifying classes, attributes and methods
Drawing class diagrams and showing relationships between classes
Applying encapsulation, inheritance, polymorphism and abstraction in one system
Structuring a program across multiple classes
Storing and managing collections of objects
Input validation and error handling
Testing: test plans, test data and iterative testing
Evaluating a solution against the original requirements
Commenting, naming and writing maintainable code
Common mistakes, such as overly large classes and weak planning

Why teachers like it

Zero prep: download and teach
Differentiated tasks that support all learners and stretch the more able
Builds the planning, coding and evaluation habits that NEA success depends on
Fully editable, so you can swap in your own scenario
Works over a series of lessons, as a holiday task or as an assessment

Suitable for

Teachers of OCR A Level Computer Science (H446), and any A Level or advanced programming course that wants a capstone OOP project in Python.
