that moment when a topic is explained better in a 7 min video than in a 2 hour lesson
@IX C - R03 Vaels International School arya yooo wassup i jus see u here watchin this video lol
Mood
why are your lessons 2 hours...
2 months lesson* 💀
@@FactFlix3 science is always a double period for me
im doing my IGCSE exams in 3 months and i think these videos are definitely saving my chemistry grade! ill update when results are out but i want to thank you for these videos!!
Same
hahaha we same year, good luck gal you gunna slay
i hav a month and just started studying guys, your prayers would be appreciated
I have my in 3 weeks. Good luck
@@wired_haus mine are in a bit more than a month, good luck tho !!
My GCSE Examination is in an hour..this is really a Good Revision..Thanks
Hope it went well!
How did it go
@@user-eu3ox9ni1j bruh 9 months late
@@benclarktighe5281 bruh 3 weeks late

How do you do it…?! How do you help loads of people pass their GCSE’s by making amazing educational videos that aren’t just easy to understand but also explain a whole hours worth of a lesson in 5 minutes still with enough detail. I’m honestly amazed at how far I’ve come just going through my curriculum on your website. I actually look forward to revising now and as I’ve got my GCSE’s coming up this May I know I need to knuckle down but as long as I’ve got this dude i know I’ll pass no question. Thank you so so much 😊
Ah thank you so much Madeleine 🤩🤩 We wish you the best of luck with your exams!
These videos are brilliant - clear, concise and well illustrated. They include great tips and examples. I am able to understand the topics and help my son. Thank you👍🏼
Glad you like them 😊
Was doing this today in chemistry didn’t understand it well till now 🙏
yeah, me too
Thank you so much! We weren’t taught this topic because of lockdown, but my mocks (which we were just recently warned about- Thanks Boris!) are in a week, this is life saving!!!
Thanks T T, lockdown sucks but good luck with your mocks!! 🤞
Easy, straight to the point, short and helped me with the QCAA syllabus. Thank you!
I just wanna inform you that your videos have been extremely helpful to me and to others as well.
Chemistry was always my least favourite subject , I have IGCSE exams in 1 months time but these videos are soo easy to understand that I now know everything needed for the exams (and I actually like Chem now)......Thank you so much :)
Ah that's great to hear Enderman!! 😊
I have 1 month left 😭and ik nothing about chem will only watching cognito and doing past paper will help?
If I knew about this channel before I would only study the last month and score a DISTINCTION?!?!?!?!?!? THIS IS AMAZZZIZIIIINNNNNNGGGGG
This is a great channel
GREAT VIDEOS!! Just love the little "addishion" at 6:32
Great video. It proved to be immensely helpful ; may God bless you Sir .
Thanks Zain, glad we could help 😊
Great and magnificent teachers like you are not getting the appreciation they deserve more than ever. We would have been glad to pay you triple to for replacing our school teacher! ❤❤ May Allah bless you!!❤
i just have one thing to say: u r a lifesaver
thank you for the information, I want to apply the knowledge I learn today🤩🤩🤩
Ong, if it wasn't for your videos on addition and condensation polymers, I would completely fail my polymer question in my GCSE paper. Thank you so much
Watching this video just 1hr before my IGCSE Chemistry exam. So well explained, thanks team cognito for your effort❤️
i remember when you were at 257k!! your channel is growing so fast :)
this channel and its videos save me from my worst nightmare of failing in a chemistry test.
I have exams in a week, thanks so much for the explanation!
Best educational channel on TH-cam ........
Thank you so much 🙏
Thankyou Amarnath!! 🙌
Thankyou so much!! Cognito is a life saverr
These videos are brilliant! I am learning chemistry properly now that I am older. You explain things really well. Where were you many years ago? Ha ha, thank you!
Thank you so much for making these helpful videos. These are saving my grades
GCSE 2024 with chem paper 2 tomorrow anyone?
meeeeee, i have 30 minutes till my paper and im watching this :/
@@Adorerania I flopped my test
Ha I have mine tomorrow😂
@@Venom-nb5dkhow was it I’m doing it next year aqa Oxford tho
Nah mines in 2 weeks
three days before the exam😂 and this is last minute session
great video!
This was really helpful in my understanding on organic chemistry, as i was struggling beforehand.
I just wanted to give further thanks to 'Cognito' and all the hard workers behind the scenes providing all of us with this great content. Again, many thanks!

you are saving my gcse thank you!!!
thank you very much it helps me
thank you sir that was really helpful 😊😊
Thank you so much for the very awesome videos! They help a lot in preparation!
you explained it so well and simply thank you so much!
Love your videos! - please can you make one on NPK fertilisers?
May Allah bless you my brother! Thank you so so much. This helps me to learn this chapter eaaaaasiiiiiieeeeerrrr. Love you man!🇧🇩🇧🇩
I have 1 month left 😭and ik nothing about chem will only watching cognito and doing past paper will help?
Never been this early for anything 🙃
This is a gift from god.
very clear tyvm
This was very helpful thank u😊
So good!!
At 1:34 you said that it would take "forever" to draw out all the monomers, however this is not true, it would take a finite amount of time
🙄
Well spotted sherlock
I love your channel omg you saved me
This is so helpful thank you
This was really helpful thanks 👍😊
Happy to help Ndapanda 😊
thank you so much ❤
Thank you so much!!!! u really helped me !!
This video was like a light shining from the heavens 🤣🤣
Happy New Year!
nicely explained
thank you very much
Thank you!You are the best teacher over world!(I think😉
Thank you! 😃
could you not draw out poly ethene while having just one carbon and two hydrogen atoms per repeating unit? and then have 2n to the right of the bracket instead of n. or is there some sort of rule that prohibits this?
Explained amazingly!!! 👌🏻👌🏻👌🏻
oh this is a very nice and interesting video, thank you so much!
THANK YOU SO MUCH!
That was useful thanks ❤
thanks
Awesome but, is this a reupload?
Yep had to fix some small errors! Usual service we’ll resume immediately 🧐
@@Cognitoedu Hehe well thank you for this!
Keep up the good work as always! :D
Love your videos!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Thks a lot for the explanation. Helped me a lot 😃🙏
Thanks Rahul glad it helped!
You saved my life
what software did you use to make these notes?
Does polymerization happen by involving other substance? Or it happen automatically when same monomers meet each other?
It does not need another substance to happen. Monomers (addition) have bonds that break open. There are now electrons willing to make bonds with anything. If they meet more monomers like theirs they are going to bind.
@@rab3795 ouu i seee
no
will you get told which monomer it is/ the name of the monomer when writing out tht equation?
شكرا هذا مفيد جدا
i love you
love you to
So basically I’m writing in 2 hours and here I am
Lmao same here
Good luck for tomorrow's test lads

Good luck! :D
please organise videos according to topics
if you visit his website linked in the description, his profile, and the end of the video, all the videos are listed by topic with practice questions :)
Thxxxx soo much
in 06:10 min isn't the molecule name 1-butene ( not just butene)???
So the polymer name will be poly(1-butene) ???
Am I right?
Hi, you could call it but-1-ene, and so poly(but-1-ene), but you don't always have to give that level of detail.
Does bond angle matter in gcse
is this for triple science??
Ye x
3:25 why are two of his hydrogen atoms at an angle, does it matter?
No.. You can just normally do that
Exam in half an hour thanks 😂😂
my teacher made me watch this but it is quite intresting
Cooolll
30 minutes before the exam
common cognito W
bruh wtf this is so helpful
what do you mean by 'unsaturated'?
meaning that they have a carbon -_ carbon double bond . The term "unsaturated" means more hydrogen atoms may be added to the hydrocarbon to make it saturated
Unsaturated means that the carbon has a double bond (which is when it has the two lines in the middle of both the carbons) and this is what makes it an alkene. Saturated means that the carbon has a single bond which is what would make something an alkane-hope this was explained alright?
@@madeleinej6048 literally what i said but ok
@@madeleinej6048 funny but my answer is actually better than yours so ye and you didn’t find any other comment to reply to?
@@reemwaleed2802 Why are you taking it so personally? They are trying to help this person too. Grow up kid, lol. You're both right anyways, stop creating issues.
this is a gregggg moment
hi, could u kindly make ur video background in black colour its more efficient in my opinion as it doesn't hurt my eyes and it more comforting to look at . thank u
Shut up
uh any IB students??
Paper 4 tmr 😂😂😂

What's that got to do with this video, this video is educational
Oh shush dude 😂, like you could help loads of people pass their GCSE’s by making amazing educational videos that aren’t just easy to understand but also explain a whole hours worth of a lesson in 5 minutes still with enough detail.
When asked to draw an additional polymer from a certain alkene monomer what is the least number of repeating units should I drawn
i love you so much thank you
This is very good, thank you
in 06:10 min isn't the molecule name 1-butene ( not just butene)???
So the polymer name will be poly(1-butene) ???
Am I right?
no
