VIDEO to support 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.

I’ve begun to self-study computer science, and I must say, your videos have proven to be a great help so far! Thank you for uploading them and taking the time to make them, they really make a student’s life easier haha.

watching in 2024. My teacher is quite boring and repeats himself a lot hence i began self-studying. Midway through the video i began to understand the material and i got to be really thankful for that.

[okanntt]

your videos have helped me throughout my exams, thank you so much

[DawoodKhan-kniu]

thank you soo much sir, will also please post videos of you solving past papers?
especially paper 2, the programming one.

I've been self-studying this course a long with a book. It helps me a lot starting with your videos then reading parts of the chapter to strengthen my understanding.

Though I have to ask, do your videos cover everything? Like, everything necessary for the exam?

[tulikarathod]

Hello! Could you please upload a video for Cyber Security (i.e. 5.3), as well?

[balaraajsubaangi]

Heyy! Love the videos as always, but youtube tells me that one unavailable video is hidden under this playlist, I am able to see The Internet and its Uses (1, 2, 3 and 4) in the playlist, which video do you think is hidden?

[agentseditz]

thank you so much sir you explained very well, .... from pak

[fareehanaqvi]

I love these computer lectures but can anyone share the physics lectures link here like these, i cant find sny good physics lectures snd have a paper in next week...

[rohansadboy]

Hello sir,
Can you share all the notes please for o level.

[codingforever]

insane idk how its so helpful... but why a coffee ☕☕ ?
