Computer Programming Practice Tests

These Grade 10 Additional Subjects practice tests introduce algorithms, variables, data types, input and output, conditionals, loops, functions, collections, debugging, testing, efficiency, cybersecurity, privacy, accessibility, and ethical programming.

Skills covered

  • Explaining algorithms, variables, data types, syntax, input, output, comments, abstraction, and operators
  • Tracing conditionals, for loops, while loops, Boolean expressions, nesting, and stopping conditions
  • Using functions, parameters, arguments, return values, lists, indexes, dictionaries, strings, and scope
  • Distinguishing syntax, runtime, and logic errors and applying testing, decomposition, pseudocode, readability, and efficiency
  • Understanding personal data, encryption, authentication, authorization, algorithmic bias, accessibility, open-source software, and phishing

How to use these practice tests

Trace the program one step at a time. Identify the data type and control structure, then check the expected output, edge cases, and security or ethical effects when the question involves real users.
