Key examiner messages
Top priorities from the principal examiner before you revise
The 2023 HKDSE ICT paper maintains a high standard of assessment, balancing routine theoretical recall with complex, scenario-based algorithmic analysis. The overall difficulty is graded as 4 stars out of 5, primarily driven by challenging questions in algorithm tracing (Paper 1,
The 2023 HKDSE ICT examination exhibits a strong focus on practical problem-solving, database constraints, and procedural trace execution.
Paper 1 contains demanding tracing tasks (particularly the custom sorting algorithm in Q3), while the Elective Papers (such as 2A Databases and 2D Software Development) demand rigorous implementation of relational logic, data validation, and programmatic dry-runs.
