Paper 2 – Application of Computational Thinking
This paper will assess Topic 6: Problem solving with programming.
The main focus of this paper is:
·       understanding what algorithms are, what they are used for and how they work in
·       relation to creating programs
·       understanding how to decompose and analyse problems
·       ability to read, write, refine and evaluate programs.
