Algorithm Design & Problem-Solving: CIE IGCSE Computer Science

#SaveMyExams #IGCSEComputerScience #igcserevision Struggling with IGCSE Computer Science algorithms and problem-solving questions? Feeling like every question looks different, and even when you understand loops and if statements, the marks still don't come? In this video, we walk you through the Algorithms and Problem Solving section of the CIE IGCSE Computer Science 0478 syllabus - exactly as Cambridge sets it out - so you know what you're being tested on and how all the pieces fit together. You'll learn: 1. What the program development life cycle is and why it matters 2. How to decompose problems into inputs, processes, outputs, and storage 3. The standard methods of solution you need to recognise (linear search, bubble sort, totalling, counting, max/min, average) 4. The difference between validation and verification (and how to explain them clearly) 5. How to use test data correctly (normal, abnormal, extreme, and boundary) 6. What trace tables are and why they stop you guessing under exam pressure 7. How to identify and correct syntax, logic, and runtime errors 8. How to write and amend algorithms that actually get marks This video is ideal for IGCSE Computer Science students who want to understand the structure of the problem-solving section, whether you're just starting the topic or struggling to turn your knowledge into exam marks. 👉 IGCSE Computer Science revision notes: https://www.savemyexams.com/igcse/com... 👉 Algorithm exam questions with SmartMark AI feedback: https://www.savemyexams.com/igcse/com... 👉 Standard methods flashcards: https://www.savemyexams.com/igcse/com... 👉 Past papers and mock exams: https://www.savemyexams.com/igcse/com... ⏱️ Timestamps 0:00 Why algorithms feel so confusing 1:00 Program development life cycle 2:15 Sub-systems and problem decomposition 3:25 Explaining algorithm's purpose 4:38 Standard methods of solution 6:12 Validation vs verification 7:10 Test data types explained 8:28 Trace tables 9:21 Error identification 10:20 Writing and amending algorithms 11:25 Summary and next steps Video to watch next:    • Data Transmission Explained: IGCSE Compute...   📱 Connect with Save My Exams: TikTok: @savemyexams Instagram: @savemyexams Facebook: @SaveMyExamsUK "What is Save My Exams?
