Assessment Guidance
Guidance for achieving higher grades
- 💡Use wireframes to plan the user interface.
- 💡Test on multiple screen sizes and operating systems.
- 💡Keep the app simple and focused on the core purpose.
- 💡Start with wireframes and prototypes.
- 💡Test on multiple devices.
- 💡Ensure the app meets the original brief.
- 💡Start with wireframes to plan layout.
- 💡Test early and often.
- 💡Consider user feedback in your review.
- 💡Use wireframes to plan your app layout before coding.
- 💡Test on multiple screen sizes and operating systems.
- 💡Document any changes made during development.
- 💡Use wireframes and prototypes in design.
- 💡Test on multiple devices and screen sizes.
- 💡Document bugs and fixes during testing.
- 💡When answering questions about computer systems, always refer to specific components and their functions. For example, explain that RAM is volatile memory used for active tasks, while the hard drive provides non-volatile storage. This shows depth of understanding.
- 💡In practical tasks, demonstrate correct formatting and layout in documents. Use styles, headers, and bullet points appropriately. Examiners look for attention to detail and the ability to produce professional-looking outputs.
- 💡For online safety questions, give concrete examples of threats and countermeasures. Instead of saying 'be careful online', describe a phishing email and explain how to identify it (e.g., checking the sender's address, looking for spelling errors).
Common Mistakes
Common errors to avoid in your coursework
- Not considering the target audience in design.
- Skipping testing or testing only on one device.
- Overcomplicating the app beyond the specification.
- Ignoring platform-specific guidelines.
- Skipping user testing or feedback.
- Overcomplicating the design without considering user experience.
- Ignoring platform-specific guidelines.
- Insufficient testing on different devices.
- Poor user interface design.
- Neglecting to define the target audience clearly.
- Skipping testing or testing only on one device.
- Overcomplicating the design beyond the scope of the brief.
- Skipping user research leading to poor design.
- Inadequate testing, especially edge cases.
- Not aligning app features with audience needs.
- Misconception: 'The CPU is the only important component in a computer.' Correction: While the CPU is crucial, other components like RAM (for temporary storage) and the hard drive (for permanent storage) are equally vital for performance. A slow hard drive can bottleneck even a fast CPU.
- Misconception: 'Once you delete a file, it's gone forever.' Correction: Deleted files are often recoverable until overwritten. Proper data disposal requires secure deletion methods or physical destruction for sensitive information.
- Misconception: 'Using public Wi-Fi is safe as long as you have a password.' Correction: Public Wi-Fi networks are vulnerable to eavesdropping. Always use a VPN or avoid accessing sensitive accounts on public networks.
