Computer Science Year 10 and 11 - paper 2 - Problem-solving and design

Show understanding that every computer system is made up of sub-systems, which in turn are made up of further sub-systems
Use top-down design, structure diagrams, flowcharts, pseudocode, library routines and sub-routines
Work out the purpose of a given algorithm
Explain standard methods of solution
Suggest and apply suitable test data
Understand the need for validation and verification checks to be made on input data (validation could include range checks, length checks, type checks and check digits)
Use trace tables to find the value of variables at each step in an algorithm
Identify errors in given algorithms and suggest ways of removing these errors
Produce an algorithm for a given problem (either in the form of pseudocode or flowchart)
Comment on the effectiveness of a given solution
