Follow and describe algorithms involving a sequence of steps, branching (decisions) and iteration (repetition)

Follow and describe algorithms involving sequencing, comparison operators (branching) and iteration

Design algorithms involving multiple alternatives (branching) and iteration

Implement algorithms as visual programs involving control structures, variables and input

Design algorithms involving nested control structures and represent them using flowcharts and pseudocode

Trace algorithms to predict output for a given input and to identify errors

Implement, modify and debug programs involving control structures and functions in a general-purpose programming language

Design algorithms involving logical operators and represent them as flowcharts and pseudocode

Validate algorithms and programs by comparing their output against a range of test cases

Implement, modify and debug modular programs, applying selected algorithms and data structures, including in an object-oriented programming language
