this man is single-handedly carrying my computer science gcse thank you

[tjstyler]

I just wanted to say thank you for the unit 1 and unit 2 videos. The revision has been super helpful, and my final Unit 2 exam is tomorrow. Keep up the good work, even if I don't watch you again! (not being horrible, promise ;) you've been awesome)

[ferless]

you have single handedly carried me from a grade 6 to a grade 9, from my mocks to my actual GCSEs!!! I am beyond grateful for your help which led to me getting 94% overall when I was averaging around 55% in mocks!!! 🧡🧡🧡🧡🧡

[crowdregs]

I've got my exam tomorrow and this was extremely useful! You've really rejogged my memory and explained everything so easily, thank you :)

[bearr]

my teacher hasnt taught me half of this stuff, i feel a bit more confident now after watching this. thank you :)

[murde_r]

Appreciate it, will use your channel for A level when it comes. Really like how you go through the exact spec

[MSD-mumz]

This is one of the best revision sources for OCR computer science ngl.... I used this as my revision source for my PPE exams and got grade 7 on paper 2 which is good considering I normally get a grade 5 on paper 2....

[issyaguado]

Will you be able to make one for A level this year?

[ChippyVix]

this guy got me 9s in evey single computer science mock hopefully it goes well for gcse

[AbdulazizAbdulrahman_]

i love this man with my entire heart man paper 1 was a breeze

[emmastevens]

got my mock tmrw this is a godsend tysm

[charizard]

This guy is carrying me through computing right now. Thanks s1perry, my savior

[Xyntorix]

S1Perry you're a fuckin' legend mate.

[sprt]

BRO IS THIS SIMILAR TO THE AQA EXAM BOARD ASWELL BECAUSE I CANT FIND ANY VIDEOS FOR AQA GCSE CS PLEASE TELL ME IF I COULD USE

[srushti]

Omg tysm s1perry....i needed this so much!!

[arty_wolf]

I don't normally comment on videos but I just wanted to say thanks - both this and your computing paper 1 revision video have been incredibly helpful =^^=

[cazoxv]

This video is absolutely brilliant, I was predicted a 7 but i think that with the help of this video i can bump up my grade as am not as good at paper 2... Thank you!

[michaelswahla]

42:10.. haha, in the exam they gave us example [1, 1]... but i did [row, column].. so did most people so I think i got it right.

[tricksterdim]

Many thanks for your videos, they have been quite adequate. Though If I must make one query; Does the algorithim section of the paper generally contain anything outside generalisation of the different programming constructs mentioned within the video? (I've been studying the GCSE independently and there haven't been too many resources out there to clarify this) Many thanks.
