Criterion C: Development (12 marks)

1. This assesses the technical complexity and quality of your programming solution.
2. It tests your coding skills, use of appropriate techniques, and computational thinking.

Criterion D: Functionality (4 marks)

1. This tests how well your solution works and meets the defined success criteria.
2. It evaluates the effectiveness and performance of your implemented solution.

Criterion E: Evaluation (6 marks)

1. This assesses your ability to critically evaluate your solution and development process.
2. It evaluates client feedback integration and identification of improvements.

Computer Science IA Grade Boundaries

1. The embedded grading tool calculates your total score out of 34 marks across all five criteria.
2. Here's how to interpret your results:
   1. 30-34 marks (7 territory): Excellent programming project with sophisticated technical implementation. Minor refinements needed.
   2. 26-29 marks (6 range): Strong project with good programming skills. Focus on increasing technical complexity and client engagement.
   3. 22-25 marks (5 level): Competent work meeting basic requirements. Strengthen programming techniques and solution complexity.
   4. 18-21 marks (4 range): Adequate foundation but needs significant improvement. Review technical implementation and functionality.
   5. 14-17 marks (3 level): Poor work with major weaknesses. Requires substantial revision of programming approach.
   6. Below 14 marks: Major revision required across most criteria. Reconsider problem definition and technical approach.

FAQs

1. How complex should my programming solution be?
   1. Aim for advanced techniques like sophisticated algorithms, complex data structures, or integration of multiple technologies. Simple CRUD applications rarely score highly.
2. Do I need a real client?
   1. Yes, you need a genuine person or organization who will use your solution. Family members, teachers, or local businesses can serve as clients.
3. How detailed should my Record of Tasks be?
   1. Document all major decisions, design changes, coding sessions, testing phases, and client interactions with dates and specific details.
4. Can I use existing frameworks and libraries?
   1. Yes, but ensure your own contribution is substantial and technically sophisticated. Simply configuring existing tools isn't sufficient.
5. What if my client can't provide detailed feedback?
   1. Guide your client with specific questions about functionality, usability, and performance. Document their responses and how you addressed their concerns.
6. Should I include all my code in the appendix?
   1. Include complete, well-commented code that demonstrates your technical skills. Organize it clearly and reference key sections in your main report.
7. How important is the functionality video?
   1. Critical - it's your only opportunity to demonstrate that your solution actually works. Show all features clearly and explain their operation.
8. What constitutes appropriate testing?
   1. Test normal use cases, edge cases, error conditions, and performance under load. Document test plans, expected results, and actual outcomes.
