I'm an Assistant Headteacher (and former Head of Computing) at a large 11-18 secondary school in central London currently teaching GCSE & A Level Computer Science and vocational IT, and leading on whole-school digital strategy. I've been creating Computer Science and IT resources designed primarily for the UK school system since I was a GCSE student myself. I've also examined and moderated at GCSE and A Level too, and am a published author.

Object-Oriented Programming: Objects and Classes
I love this. I am thinking if I can memorize an entire binary code of a recording I could have that recording in my head and just have to input it into a computer lol. I always wanna peserve data and if I could teach myself this and expand my mind in these ways I'll feel I'm using my gift of life in many ways
i never pay attention during lectures so this has been helpful<3
Damn that accent
i go to ur school and clocked who u are LOL
yo sir i go to ur school that u teacher LOL i was in ur year 9 class
Who else trying to unlearn the OOP dogma?
Awesome, crystal.clear and concise. I really found useful the second example, where you go strait and perform filtering operation. In many cases an inner ou nested query would have been used to solve that one but I persornally find it hard to read subqueries under the where clause. Thank you for the insightful tutorial.
thanks for a detailed information!!1
You're hard to understand... the accent is atrocious!
incredible explanation! 👏🏻👏🏻
An Hours to the Exam 😂
Taking A level computer science without ever doing the gcse these videos are saving me 🙏🙏🙏
I got a mock tommorow at 9am, I decide to start precision at 11pm the night before.. Im cooked
what about 0100 on arthimetic left shift the double fits the size but the sign is changed
100% value. Thanks!
"The answers to a multiple choice question" is Qualitative. The order of the choices doesn't matter. Also, they could have been "option 'sky'", "option 'earth'" instead of "option 1" and "option 2", where the fact that they are numbers in the last case is just circumstantial.
For the possible structure in the Analysis section, 4. how would I differentiate that researched problem from 2., to a paragraph of problem in 4. (if that all makes sense)
Im doomed as fuck for PAPER 1 but good at PAPER 2 although i frogit the topics and stuff
ICO are needs to be truely independent
Frequencies below and above we feel them with other natural ways - You know that we have more than ears to feel above and below frequencies - colours are frequencies smell also and all around us are waves/frequencies. Digital for now can not show the reality of analogue sounds and colours or other waves/frequencies many are missing - our bodies and nature around us have gazillions frequencies we don't "listen" all with our ears.
So if we as a small business covertly recorded a business meeting with someone from a company that was in the middle of screwing us over because we were at risk and wanted evidence would this apply?
Test in 1 hour let’s hope this works
why are the arrows always discombobulated.
I found this channel 30 mins before my test, I'm cooked
hey 2024 students whos teachers failed them

“With great power comes great big booty bitches” - Uncle Ben
about to write my exam in 3 hours👍(IM COOKED)
Thx, for this although the paper i will be doing tomorrow will de different due to the year, this walk though has still help me thx you. (11/06/2024)
Thx you so much, i have an iMedia ICT exam tomorrow and our teacher wasn't able to teach us any of the theory content all we did was the NEA littraly so i was littraly going into the exam blind, but after doing a lot of searching i came across your videos and they have realy help and i'm confident going into the the exam, thx you so much for making, due to lack of easy accessible revision on this specific topic, most of the time when i search ICT creative media it just comes up with computer science, so again thx you so much. MUCH APPRESIATED
watching before gsce final exam
i saw someone say last minute revision 3 weeks ago i just started now, its officially over.
This was a great video. Thank you very much!
What this mean u can take exam twice
Can you get a grade 8 in this exam or is it just either a 7 or a 9
I'm not even lying or exaggerating at ALL when I tell you our teachers taught us NOTHING. Ever since the only good teacher for Creative I Media left us in Year 8 we just had rotation by rotation of random cover teachers who were as confused as we were and ha only the day after tomorrow is My written paper. SO THANK YOU SO MUCH FOR THIS BECAUSE I'M COOKED
that sucks... my imedia teacher is okay... but he doesnt really know how to teach either, hes a great guy though, but he just made us do work "independently" and this causes people in my class to misbehave and its embarrassing.. i sit alone so its just so unhelpful. Goodluck for monday :)
@@literalchad Damn ngl we all just did our own stuff - Thx Good luck to you too!
literally same my teacher does not know how to teach so now i’m binge watching a bunch of vids for monday lol. good luck!
My teacher only helps us with the coursework but has never once taught us anything with the theory
What did you lot get in coursework
Great video, was very helpful!!
I got 65/70 in my project and i did 85% of it in 3 days, wouldn’t recommend it but it’s doable so don’t stress. The project is light
Help me
@@elishalol33The biggest bit of advice I have is to not leave it to the last minute. Do you have an idea already?
How did you do it in 3 days?
What a explanation😍, will never forget how call stack works. Thank you.
