I recently purchased your AS and A Level slides, and I am thoroughly impressed. The slides are well-organized, visually engaging, and make complex topics easy to understand. These UA-cam videos further help & support the usage of those slides too. I highly recommend your resources to anyone looking to save time for teaching or learning using your resources! Thank you so much. Keep up the good work!
your O level videos helped me through O levels so much, thank you so much for making A level videos haha I think I even requested you to make A level CS content in one of your older videos omg im kinda hyped tyty
Sir you are the besttttttt mannn ever sirrrrr May God Bless you alot I am now in gcses but still I am very hopeful now to see you making lectures on A levels may GOD bless you alottt
hii, I just noticed that in 12:10 your answer is incorrect, shouldn't the digit value of A be 10 and E be 14? I assume that the right answer is 4782... besides that im really glad I came across your a level playlist, I'm feeling more confident about my preparation for cs exam thanks to you, hoping to see more content based on a level cs!!
36:00 if 2 byte code always start 110, and the second and third Bits in one byte can be 1 or 0 then wouldn’t that mean that it is possible to get a 2 byte code starting value in the one byte code? How would the computer identify what byte code is being use? this also apply to 3 and 4 byte code as well?
110X XXXX 10XX XXXX the solution for that ^^^^^ the first bits of the first byte of a 2 byte unicode always start with 110, and the second one always start with 10
Just started my as level year, these were very helpful in igces (even though we didn't have the paper1 in mj 23 😂😂) still helped me through out my internals!!!
@@ali12414did you use him the entire time? if so please lmk if he was helpful and if he helped your grade, sometimes i feel these videos lack enough information like advantages and disadvantages as seen in the past papers
Hi I have a question. At 29:00 let's suppose I get a byte in which my right nibble is incorrect (bcd) but my left is correct and even after adding the correction nibble and the carry, the left nibble it is still correct (bcd), do I still need to add the correction bit to it.
No, you wouldn't need to add the correction bit to the left nibble in that case. Since the left nibble is already correct and within the valid BCD range (0-9), you can leave it as it is. In BCD adjustment, you only need to add the correction bit (usually 0x06) to nibbles that exceed 9 or if a carry flag indicates an overflow. If the left nibble remains correct after processing the right nibble, adding a correction would push it out of the valid BCD range. So, you should only apply the correction to the incorrect right nibble and leave the left one unchanged if it’s already correct.
Dude i really hope this video works, started doing CS this year in AS never did it in O Level and im really behind please please please work (if it does im coming back to comment in 2 weeks)

u made a mistake at 12:03 E in hexadecimal is 14 not 15, F is 15
Sir from Where Can I get your Slides Of A Levels
Love your work sir
is this playlist contains all the cs alevels content ??????????
Yup, and they’re really detailed
you are amazing, helpful and complete. THANK YOU SIR
I was wondering if anyone has the answers for the Exam-style questions from the course book. Or if James could do a video series, that would be great.
hi got an B for a levels thank you for you help

the solution for that ^^^^^
the first bits of the first byte of a 2 byte unicode always start with 110, and the second one always start with 10
Particular character codes are not expected to learn sir!?
Correct me if I'm wrong but at 34:59 3 byte one should be 2^16 not 14.
Is this a mistake ?? coz other byte seem to align except this one.
in my perspective the correct one is 2^16 with 65,536 combinations. regardless, this video is very helpful for me.
Thanks bro
I dont understand how you are so intelligent 😭
Thank You!
are these videos also useful for AQA alevel
Thank you so000oo much for this! :)
Just started my as level year, these were very helpful in igces (even though we didn't have the paper1 in mj 23 😂😂) still helped me through out my internals!!!

Thanks sir
pls do a level physics
It’s ready! 😉
can you please make two playlists for as and a2. it would really be helpful
Hey james! Your videos are amazing. Just a question, are you interested if you do computer science course video for the IB program?
I'm doing AS right now (first year of A-levels) so which topics am I required to watch, study and practice?
Chapters 1-8 for As level

Can you do the Cambridge physics for AS to please
can you understand Urdu then I'll recommend a perfect channel for physics
