This video provides a clear and exam-focused introduction to Count-Controlled Loops—one of the foundational iteration structures in O-Level / IGCSE Computer Science (0478).
Count-controlled loops are essential for solving repetitive tasks in algorithms, especially in Paper 2, where you frequently use them to process lists, generate sequences, and repeat actions a specific number of times.

In this lesson, we break down exactly how FOR…TO…NEXT loops work in Cambridge pseudocode, how to trace them, how to write your own, and how they appear in real exam questions.

📚 What You Will Learn

✔ What count-controlled iteration means
✔ How the FOR…TO…NEXT loop works in pseudocode
✔ Understanding loop variables (counters)
✔ Incrementing and decrementing loops
✔ Loop boundaries & off-by-one mistakes
✔ When to use FOR loops vs WHILE/REPEAT loops
✔ Exam-style examples and trace-table walkthroughs
✔ Common errors students make—and how to avoid them

🎯 Why This Lesson Matters

Count-controlled loops appear in nearly every Paper 2 exam. You’ll need them for:

Processing arrays/lists

Generating repeated outputs

Summation and counting algorithms

Validation with fixed attempts

Simple simulations with a fixed number of cycles

Mastering count-controlled loops helps you build confidence with all future iteration topics.

💡 Perfect For

O-Level / IGCSE CS (0478) students

Anyone revising iteration & loop logic

Students preparing for Paper 2 exams

Teachers needing a clear, student-friendly explanation
