such a handsome professor!! 😍this was indeed very useful
3:17 is the data type PRODUCT case sensitive? You Type PRODUCT but Declare Product.
minecraft carbon cube 💔💔💔💔💔
great vudeo! (3:26 caseoh doing sports)
thank u so much for helping me understand this topic
WOW!!!, i found it very helpfull , thank you very much
I hate u and everything u stand for
The code in 42:23 have a mistake. It does not output the corresponding number of spaces after the symbol in each line.
thanks bro i will never forget your teachings for me before my tests after 1 day and i will always thank you for every letter you said to make me or us understand thank you James Gan
Which app do you use
you just helped me with physic and now computer science , and your videos are easy to understand , thank you a lot .
Hi I have a question, do we have to remember all instructions like the name and what it means, because I’ve heard there will be given a table with them on the exam
first view
This helps a lot. Thanks!
at 37:09 can u do the same thing with a repeat until loop?
After A Levels can you post IGCSE Mathematics. Please please please 🙏
"...If there are voices that humans cannot hear," Excuse me.
Finally finished first video and it's really helpful Moving to the next one 👍👍
do you work as a teacher? where do you work(if not secret)
shush
exam cracker fr
यह तो मोमेंट का जाईज़ा है।
love your videos, helped me get a 93 in computer science igcse!
@JamesGan are chatbots like chatgpt and gemini expert systems?
Where can I get the same questions as your doing. I really need them. Also the vedio is cool ❤❤ I love it
oh my god tysm i was waiting for waves since soo long, i am writing feb march soo i have my boards in like 12 days now, i wish u could do all of waves before that it would really help me
Nice keep it up🎉 Can u give me shout out
he may save my exam because my teacher copies him
Helpful video can't hear anything though, please use a better mic. Thanks!
I finished my IGCSE exam in June 2024, I got a 9 for theory because of these amazing videos, they are really a big help. Keep it up!!
Thank you🥵
can you like create a vid that summarises the whole syllabus
Sir I am a student of 9618 computer science I want to ask that pseudo code along with comments is more preferable by examiner . If more preferable can you provide us the video in which you teach us pseudo code along with comments
Aren't these notes copied from or in Znotes.
❤
Can u pls send this video or ppt ?
😍
Thank you for that explanation
❤
does this cover extended physics
Erm but I think u forgot to put up the videos that u mentioned , in the description
Thx mr Chris
Couldnt understand binary shifting
coming here because for some reason i decided to take as levels while not having any experience of cs at all. im cooked chat 😂😂
HI James, I got some huge news and a story. I was doing the local syllabus of our country, but it was a less qualification to fulfill my dreams, so I tried the Cambridge one's as it was a great one for international recognition. But it is costly, and not a free one, so my mom could just promise me the exam fee's. I determined to do everything as a self-study session, in any free way possible. So, I came to Yt, and searched the Subjects for the guidance I needed. I went to classes for Lit and Eng, but they were not continuous as our family's financial status fluctuated so much. I did 2024 Oct Nov, and yesterday I got my results. I did 7 subs, and I got an A* for Comp Science. As of others.... 2 A*'s for Maths and Physics.... 3A's for Chem, Bio and Lit.... and a 77-B for Eng (I'm a bit sad for that one). To tell you, I never went or attended classes for Comp Sci, and not even any single family member knows a drop of this field. I just wanted to start doing this, as my crush at that time was doing that. Now I have no crush on her, but a love for Comp Sci and an A*. And the Only teacher is you. When I told my friends that I did this Paid examination, just by learning from YT, and they just laughed.... and today, I can make them wrong. And it was all you. I loved your content so much.... You actually made self-study for free possible... The betterment of your Programming lessons cannot be expressed, as I never had anyone to correct my Pseudocode's, or mark my practice papers. I was scared thinking I'll mess up just tryna do it all alone. My marks are 96- A*, and the Only part I could get wrong was the truth table pseudocode in 2024 OCT/Nov programming paper which had STEP VALUE command which I'm not familiar with. And a SSL certificate part, that I hadn't noted down correctly. However, all are done, and I'm so much happy. As everyone would know, those bloody relatives are mocking for that B as I couldn't get an A despite the fact that I was writing English books and Poems. And for all others, I'm just saying, if you have the will and the dedication, you don't need thousands of money for classes, you can just study from YT, as there are channels for all subjects that post quality content, in whole of the whole syllabus. And these kinds of creators are always there. Lastly, if anyone interested, I'll tell the channels who I referred to, and Mr. James.... Thank you so much. I'm forever grateful and pls keep this helpful project on....
congrats!
explain how you could use a plotting compass to investigate the magnetic field around a bar magnet?
the best video for this chapter ever. i got an exam tomorrow and i was streessing for this chapter soo much untill i saw this video. ITS SOO GOOD TY
I followed your video for my kid for IGCSE exam October 2024 he passed and I convey thanks to you and your efforts
thank you so much, i can't express how much you've helped me
thank you so much, with the help of your videos I went from scoring C's in my monthly tests, to A in my midterms ❤
Hello, I was wondering if I could get these slides?
