Hello Mr. James, I’m an AS Level student preparing for my May/June 2025 examination. Your channel rocks me with a huge number of videos and they are so amazing. Thanks for your guidance. Could you help me with some paid classes online for CS?

[upper-Machine-]

I got an A* becuase of you. So happy you have started AL CS. 😀

[gameboyfrank]

thank you James, this is so helpful and so detailed! I studied with the video and I found it is much efficient and so much effortless!!!

[randaadel]

THANK YOUU SO MUCH FOR THIS YOU HAVE NO IDEA HOW MUCH THIS HELPS ME PLEASE MAKE FOR THE WHOLE A- LEVEL SYLLABUS

[InshaShafiq-yb]

if I get a good grade in As level CS, all credit goes to you.... I do not understand my teacher that much and so my whole CS is relying on your videos😂🥰

[leila]

These are lifesaving! thank you so much

[hmmYeahIDK]

Damn your video and audio quality has come a long way

Hi,
Woa, glad you started posting for AL CS. I am a science student was wondering if I could take up CS by myself. I’m doing 4 subjects already, so going for 5 would be messy, so I’m wondering if I’d be able to do it myself.

Just to get an idea. Would I need a teacher for AL computer science to cover the syllabus? As of if there is everything I need in the textbook or if there are more stuff that I need for the exam, that I would be learning specifically under a teacher? If yes, can you give some specification on that?

I haven’t really started CS yet, I still have much going on rn, to start up with CS. Would be grateful if you could reply.
Thank you.
