i have no computer science teacher and my whole class is cooked
do you have much on web technologies???
Please please do more A level Content i’m begging you, YOU yes YOU got me my GCSE not craig and dave. 🙏

thank you for sowing me to bullied my python pogroming
This was really helpful, could we get more videos on this for Paper 2 content?
🤑🤑🤑🤑🤑🤑🕳💥tahnks! muy helpfu;!
Cheers Mate
thank you very much i was able to understand alot better now!!
An example of a library could be NumPy in Python? 🤭🥺🤓
thanks mate
pseudocode to store a name, age, and favorite color for a user profile START DECLARE name AS STRING DECLARE age AS INTEGER DECLARE favoriteColor AS STRING PROMPT "Enter your name:" SET name = USER_INPUT PROMPT "Enter your age:" SET age = USER_INPUT PROMPT "Enter your favorite color:" SET favoriteColor = USER_INPUT OUTPUT "User Profile Saved: Name = " + name + ", Age = " + age + ", Favorite Color = " + favoriteColor END
for 4:15 do I get 2 marks for saying Router uses ip address and switch use mac address or would i only get one
for 4:15 can i say they both communicate with devices and another one can i say theyre both a central point
I just love u 4 this . Love brov

Watching before exam thanks tomo

in the second to last karnaugh map example, why does the yellow box not extend by another position to make a box of 8 1's instead of four?
This is all you need to know about floating point for OCR? Got CS exam on Monday
Yeah, converting, adding, subtracting floating points. Look at physics and maths tutor notes for topic 1.4.1 to check everything

I was wondering if you could upload answers to the tests as I'm not sure if I have gotten them correct or not
Where can I get the paper
Erm, what the sigma?
Brainrot.
@@ram10- stalker
Where do you get these papers, sir?
I have hope for a grade 8
Bros beard is magnificent
love u sm
what are the answers?
Hi Sir, By any chance can you do Paper 2?
Tks for the video. Do you have the mark scheme? I just can't find it on the Internet
they realease it after like 3 or 4 years after the exam i think, but only schools and tuition centers have access to them (paper and mark scheme)
i got my exam tmrw :( my teacher said that the WAP should clearly be labeled for the question at 24:46
cs is too ez bc of u
This gives some nostalgia 😂
Hi Sir, I hope you are doing well. I wanted to attempt this paper so I can watch the walk-through afterwards. By any chance where can I download this paper please?
the ocr past papers website
@@TheCrowConstellation wwsggg
The 2023 Paper is not on there
@@bea7015 request it from your teachers then it may not be available to the public yet but teachers have access to them
@@bea7015 its not realeased to the public yet, probably gonna have to wait for 2 more years i think
Thank you so much for this sir, these are so helpful. Could you go over the 2023 Computer Science Paper 2 too?
Yes, soon!
Oooh that last question brings back memories. Had to cross everything out and redo it in the last 10 minutes of the exam.
Thank you😄
I love how you explained the last question my teacher's way doesn't make too much sense!
No comment for 4 years but these exam questions videos are super super useful especially as a lot of the questions especially the data types ones are tricky and confusing. Thanks!
YOUR BACK🎉🎉🎉🎉❤
nice video but for the first question you got to make it 1 to 101 because the for loop will always stop one number behind the stop value
In Python I completely agree, as the logical test in the for loop is essentially < 100. However, in this pseudocode, the value is inclusive of the value is the logical test is essentially <= 100. In python however you would write something like for i in range(1,101). I am no longer teaching AQA Computer Science, so it might be that their pseudocode has changed?
great video
This is so helpful I'm doing my hsc and my teacher is on vacation and this video is saving my life
It is a crime that this content was ignored by viewers
