Hi - we make video lessons for GCSE science and maths. The lessons give a concise run through of everything you'll need to know for your exams.
Each video has been designed specifically for the 9-1 GCSE courses, and although they most closely mirror the AQA spec, everything you need to know for the main exam boards will be covered.
We also have a website where you can work through the lesson videos and answer a series of practice questions to check you know all the required learning points. All your progress is automatically tracked, and you can sign up at www.cognitoedu.org
Best wishes,
Amadeus & Tom

If you go down to the actual spring material, it is in fact a very thin long metal rod, wound into a coil form. If you observe closely what movement a spring is undertaking during compression or stretching you will observe that the this action is actually the bar twisting of equal amount throughout its entire length.
cuz of u i got 9s in triple science ur a legend man keep up the good work
so if the plant was at night that means that the stomata will be closed because there ain t no sunlight to absorb and be able to photosynthesise am i right
Awesome. It was simplified and to the point.
Really helpful! Almost at 1MIL!!!!!!!!
Bro ur vids r the best!!! I watched one of the chemistry ones and literally the next lesson the teacher shows it saying, watch this video. Cognitive videos are entreating and very educational! (I agree with this)
Just saved me thank you 😭
pov: got a math test tmr and this saved my life ngl
thank you so much you have videos on everything
You just gain a subscriber sir Welcome and congratulations i really understood your lectures ❤❤❤ from Cameroon 🇨🇲🇨🇲
How are you soo good! Thanks for the help, understood everything!
Where did bro go 😭🙏

Muslims were the first to work with elements and they invented soap and distillation processes whihc relates i guess
I home school
I love ❤cognito the animations maths physics science bruh is built to help us with our GCSE prep
his 6 hours playlist gave memore information than my 3 years of chemistry in school
tysm bruv life saver
Bro this is replacable to my teacher
Thank you Cognito, you have been a great help with Chemistry. I DONT KNOW how I would've made it if not for you there are no very good chemistry teacher's for IGCSE in the area, so I had to settle with the best of the low. But your videos came extremely handy. Thank You
this is gonna sound weird but am i the only person who finds his voice really relaxing
My igcse in 3 hours lol
How did it go?
Hey he said the yellow peas were dominant, if thats the case why are all peas now days green pods?

That video was short it that really all we need to do wow 👍
I am watching this right before my cies
i leave for my igcse bio p4 in 20 minutes and i’ve been watching your videos for at least 2 hours 😭 one of the best science channels out there
As someone who is studying this on a science level to better understand solar flares. Your break down is brillent
You were speaking a bit quicker in this video!
Thank you so much for doing this! I struggled so much with this topic, but here something just clicked, and I understood it!
I'm a bilingual person. I have never tried improving my academic levels by my 2nd language (English) and all dependent on my home language. However , after reviewing a small lesson from the book by this video I always studied in English since then. I was encouraged by this video to step even further in this route . And I truly appreciate all the hard work this creator has sent in his creations🙏thanks g
2024 to pass my finals!!!

I have my exam tomorrow and rn i am binge watching all your videos....
Blud I've got 3 days for my IGCSE exams and I was thinking I am doomed but I'm glad I found this channel... now IGCSE feel like a piece of cake... tysm!
This is not the igcse syllabus
This is the best topic for me :DD
pretty sure this is AI generated
What.
Learning more than the textbooks itself.
