Coding Challenges for GCSE and A Level Computer Science

Attached is a collection of coding challenges. The best way to learn and get better at programming is to practise, but it is often difficult to know what to make. Working through these challenges will increase you skill set and familiarity with programming. 

Remember, we program using python in high school (years 7-11) and C# at sixth form. 

Programming IDEs (or you can code online using Replit)

Python: Thonny, Hartismere python online (no saving)

C#: Sharp Develop (old but lightweight), Visual Studio Community
