Programming & Code Tracing Technique

Paper 1 of the AQA A-Level Computer Science exam places heavy emphasis on your ability to read, trace, write, and debug code. This lesson covers the specific techniques you need to excel at code-tracing questions, write effective solutions in AQA pseudo-code or a named programming language, approach algorithm design questions systematically, and avoid the common mistakes that cost students marks.
