This lesson covers the OCR A-Level Computer Science Non-Exam Assessment (NEA) — the programming project worth 70 marks and 20% of your A-Level. It explains how to choose a project, structure your analysis, design your solution, implement it effectively, test it thoroughly, and write a strong evaluation. We also break down the mark scheme and highlight common mistakes that cost students marks.
The NEA is a substantial programming project that you complete during your A-Level course. It is internally assessed by your teacher and externally moderated by OCR. The project must demonstrate your ability to analyse a problem, design a solution, implement it in code, test it, and evaluate your work.
