🚀 Cambridge IGCSE Computer Science Logic Gates | NOR Gate, Truth Tables Paper 23 (May/June 2025)

Do you know that logic gate and logic expression questions are some of the EASIEST marks to score in a Computer Science exam? 💡
In this video, I prove it step-by-step using a real Cambridge IGCSE Computer Science Paper 2 question (Component 3, May/June 2025).

We cover:
✅ How to draw the symbol for a NOR gate
✅ How to complete the truth table for a NOR gate
✅ How to translate a real-world problem into a logic expression
✅ How to build and complete a truth table for a security system
✅ Exam tips to avoid common logic gate mistakes

This lesson breaks everything down slowly and logically, making it perfect for:
🎓 Cambridge IGCSE Computer Science students
🎓 Exam revision and last-minute practice
🎓 Anyone struggling with logic expressions and truth tables

📌 Key Concept Covered:
Alarm sounds only when it is dark AND when motion OR sound (or both) is detected — explained clearly using logic gates and Boolean logic.
