After two and a half years of putting off revision, and my GSCEs coming up in less than five months, i really appreciate this video. But listen, don't do what i did, if you are in younger years, i beg of you, start revising because i have never felt so stressed in my life :)

So in a seven minute video, I learned more than what the teacher took an entire period to teach us, and this guy taught it much better than the teacher!

I’m in year 9 and because I’m someone who bases their learning off of understanding rather than just knowing a simple answer, this really helped me because my teacher just told us all we need to know is the definition, ‘same number of protons, different number of neutrons’. As I’m doing the higher paper for my test next week, I find this super helpful.

I’m a fool who had been paying school fees just to get hated by teachers. This is free, short, better and available all the time. Thanku so much Cognito!

These videos are so useful and these will really help me do well in my gsces. Currently I'm in year 10 and I really want to do well so I have started revising early. I don't really learn a lot from reading or writing, I'm more of a visual learner (I learn better from watching videos) so these helped me so much and I'm sure so many people watch your videos and learn a lot. Thanks so much I really appreciate all the effort you put into your vids❤️

For anyone who is below yr 11, or even in the beginning of yr 11, start revising now, currently the day before my chem paper 1 and I’m stressing tf out, just started revising today after my maths paper
Wish me luck 😭😭😭😭

Amazing video! I’m confident I can now explain ‘relative atomic mass’ to my daughter. Thank you 🙏

1 am 13 years and i am writing my igcse in 3 months cognito you are a real blessing

I'm about to start 10th grade next month, and I really struggle with Chemistry. I recently watched a video suggesting that I target my weaknesses before going back to school so that I am prepared, and that's where these videos come in. These videos have been incredibly helpful, and I can't wait to get back to school and show off how much I know about Chemistry lol.

hi cognito!! i’ve back here again for the third time, i have mocks in a month on paper one for chem and these will finalise our science pathways, you’ve already helped me get moved up to do triple, and now you’ll help me stay there. Your videos are such a big help to me, thank you so much for posting these videos!

[ahmedhassan]

You are the best teacher I have ever seen.

[duazia]

Awesome videos! Never stop doing this, Tom and Amadeus! You guys have no idea how many students from all over the world are dependent on you!

[gatito]

You’re really a life saver! It’s impossible to understand this in classroom but you make it much more easily to understand

helloes cognito :D

thank you so much for your work!! My science teacher confuses everybody in grade 8, but most others have tuition to help them along, so I don’t understand anything which goes on in science..

My science teacher said recently that I was going to fail my EYAs (end-of-year exams) and I’m all hopped up on spite to prove him wrong, but didn’t know how.

Your videos are my saving grace. Thank you so much <33

[julip_bear]

you’re an absolute legend, mad respect. Thank you <3

[nddcdkm]

Respect man your really helping a lot of students with their exams

[AureliaObonsi]

this video has really helped i will be able to understand relative atomic mass perfectly thank you

[dvrina]

hello cognito!! i have written tons of thank yous after my 3 major exams which determine whether i do triple or double science
today was the day i got the email and i did end up getting triple science
but i have to give you a big thanks for helping me passing those exams to get into the pathway i wanted
thank you so much cognito i am so happy!!! i wish you all the best with your channel

[crabinfestation]

Super useful since our teacher refused to explain what abundance is, thank you so much! The visuals really help <3

[chloemulcahy]
