Computer Science Syllabus
Cambridge IGCSE™ (9–1 0984) (A*-C 0478)
For exams in 2023, 2024 and 2025.

Cambridge IGCSE Computer Science helps learners develop an interest in computational thinking and an understanding of the principles of problem-solving using computers. They apply this understanding to create computer-based solutions to problems using algorithms and a high-level programming language. Learners also develop a range of technical skills, and the ability to effectively test and evaluate computing solutions.

Studying Cambridge IGCSE Computer Science helps learners appreciate current and emerging computing technologies, the benefits of their use and recognise their potential risks. It provides an ideal foundation for progression to Cambridge International AS & A Level and is valuable for other areas of study and everyday life.

Sir. I am planning to do Cambridge o level on 2024 May/june. So if i follow all of your videos and if i follow some past papers, Can I get a A* for computer science ?

Hello sir, first of all thank you so much for posting these videos!! I recently saw somewhere that for two's complement there's another method where you write the negative number as it's positive form, then u flip it (write it in reverse order like the division method) and then u add 1. Is this method good??

Sir in the Logical Binary Shift at 6:46 why did you shift by 5? Shifting to left by 4 also gives you

Hello sir please make a video on binary addition

[yashneilmadrira]

Sir, how do we know when the number is negative and when it isnt. what if there is a one in 128 because the number is that big?

[yasminbibi]

Your voice is so harsh and hard can't understand nicely. Please add other voice that is soft.
