My channel primarily looks at the Computer Science across the Key Stages of the British and International Curriculum. I have also included a series of videos which cover each topic from the Syllabus for the 2023-2025 Cambridge IGCSE. There are also examples of how to best answers exam questions from both papers 1 and 2 of the iGCSE.

🤩 Thank you so much for your support... it means a lot! 😍

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.

Rlly good video. SQL has been a pain for me for a year now and this video with examples is JUST what I needed

Super useful stuff ty mate!

[germanos]

you have done a great job educating me please continue to do so with other future generations

Thank you very much! Will we have to write any SQL from scratch, like with pseudocode?

Hello sir ur videos are amazing plz also make videos on exam style questions at the end of every chapter in computer science igcse book kindly

[ChadonTop]

hi! do u have any suggestions for which website we could use for topical past papers (for this chapter)?

[schoolsteachers]

Dear sir, your videos are realy helpful. can u give me some Wave side address for practice

[Kenziior]

Can you please do a video solving questions on it

8:04 I just want to bring up that I believe you got the rows and fields mixed up. According to the IGCSE & O level book, you seem to have done the opposite regarding the fields and records..

Please do make sure of such information. I could be mistaken myself but after checking the confusion had passed

[CloudOnIOS]

Just a quick question, does the primary key count as a field or is it not counted? Like if I’m asked a question to fill a table with 7 fields and I do, but add a primary key at the start after it, would it count as 8 fields or 7?

[mahnoorsufian]

sir are these lectures also regarding the 2210 syllabus of computer science??

[idekanymore]

Would you mind doing some questions on this (SQL)?
