    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?

      @@fizzazaheer9509 just start early
      Be consistent and use TH-cam, some of the stuff won't make sense at the beginning but give it time.
      Also use past papers like really makesure you study a topic and then go straight to past papers.
      I know it sounds like easy like it's just 4 subjects right.
      I went from being an A* student to a D student.
      I would suggest you start early. It's one of my biggest regrets.

    Hi Mr James. The mode of transmission for the three topologies, excluding bus topology, you wrote as duplex. Is it half duplex, full duplex or both?

    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.

      Hello Tharushi, this subject might not be that easier for you if you don't have a teacher. But you can still do it if you are dedicated in doing the past year questions. Just need to make sure that you have enough time for that :)

      Hey Tharushi . I am also planning to do so, but don’t have a proper idea if it’ll be hard to do 5 subjects. Can I know ur opinion ?

      @@riadulislam4849 Hi,
      I’m not really sure of it as well. I’m currently focusing on 3 and when I feel like i have time, I’m doing CS. But I won’t take it as a priority.
      So I’ll see how it goes like this for a few months and if I feel like I could cover CS well, and manage all of it. I’ll keep doing it.
      Depends on you, there’s a chance you will be messing up all four, if you don’t have a proper schedule.
      So i feel it’s better to have 3 on the priority list and have the others on the side like a hobby. So you can take it in and out of the picture depending on the situation.
      And if it seems like it’s not possible to manage all, just resort to three or so. But it highly depends on your expectations for your results. So, resort to something that personally goes well with your pace.
