How we mark Computer Science

1. Trace your algorithms

Flowcharts, pseudocode, and code outputs read and evaluated step by step.

2. Mark theory precisely

Data representation, networks, and ethics answers checked for required terminology.

3. Fix logic errors

Off-by-one errors, wrong operators, and missing base cases explained specifically.
