A. Know the key terms
Ensure that you have found your own definitions for all terms in the ‘additional terminology’ on page 9 of the case study.
A possible (not veritably correct!) list is here: Paper 3 Key term definitions
B. Do the research
Make sure that you’ve done detailed research on each section of the case study, including:
- Bangbai’s CAD system
- Problems of scale
- EMIS for Bangbai
- Emergency services app
- Reporting non-urgent issues
- Emergency response vehicles
- Multi-tier architecture and scalability
- Load balancing algorithms
C. Rehearse possible challenge answers
Practice writing longer responses to the 5 challenges faced towards the end of the case study. These questions will usually be assessed using the Question 3/4 marking bands grid.
