Paper 2 – Practical Problem Solving & Programming
The Computational Thinking exam covers the programming theory topics. A set of programming tasks will be set covering the first section of the exam.
Whilst you are not required to actually program these in the exam, nor submit your code, you are required to answer questions about them and write reflective algorithms for o of the tasks.
This is a 1 hour 45 minutes written paper that includes multiple choice, short answer, and longer answer questions including written code questions.
