Ignite your students' programming potential through a creative approach to Computer Science
Through a practical approach that balances traditional and modern computing methodologies with programming and creativity, our International AS/A-level Computer Science course develops the skills needed for the future.
- Places on-screen programming at the core of the curriculum, developing the skills integral to further study of Computer Science in today’s world.
- Continues the choice of programming languages (Python, Visual Basic or C#) from International GCSE so your students can further their skills in familiar, globally relevant programming languages.
- Seamless transition from International GCSE through shared assessment objectives and familiar assessment structures.
