Honestly, Ive been so bad with my science, even until now when I am in year11. I`m getting grade 3s and 4s in science which I don't like, but I`m never going to give up. I`ve only watched 3 from the start of your chemistry playlist and I`ve learnt so much. I love your videos and as coronavirus has stopped exams, I can try harder to get grade 7s. Thank you so much!!!!
Hi , thanks a lot for all this information that you put in the videos , last year I submitted a biology and I passed in it , all I did was prepare for the exam by studing your videos . Thank you for the helpt that you provide us in the simplest way .
I swear I went through stress trying to understand this from my school book,for the exam tmwr. thank you so much, you have made it 10x’s more easier to understand
I am in Year 8, revising for Tests and these videos are so simple and easy to understand. When revising, I would always recommending searching for the topic on this channel.
Ive always been interested in science and ive recently started learning this topic. But our science teacher does nothing but berate how much of a dumbarse we are compared to his generation, with only 30% of the time spent on teaching us. So here i am scrolling through google and youtube for a teacher that actually cares about their students. Love your video!
I’m studying for this science based competition which is hard to study for because the material is on new topics, but you make it so easy to take notes, revise, understand, and practice! This is my favorite science channel!🙂🙂
Ngl, this channel is AMAZING - helps u with exams, revision and u can learn topics u haven't even studied in lessons which makes u top of the class. Thank u so much, I really appreciate ur videos. Keep continuing and pls don't stop!!!
The video series so far is very well explained, i like the fact that you are not in a rush to overwhelm us like most other channels. It feels like i can genuinly learn and digest the material, my compliments and thank you!
my whole class watched your video in school on the screen by our teacher . thanks for making good videos that actually help everyone not just get views.
Thank you so much! U have saved me! U making diagrams and using a visual reference really helps me what it actually looks like. You also speak in good pace so its easy to understand
ahhh you helped a lot with every video you teach. This video is what I always have to replay because I tend to forget this (I have a chemistry and biology exam paper today) but you’ve made this incredibly easier (even when it comes to Maths).
OMGGGGG... God sent you to me.... the best videos ever I WILLL RECOMMEND it to everyone I know.. Thanks God you have videos on all 3 subjects that I'm doing Thank you so muchhhhhh
Thank you for these videos. I've got my Chemistry GCSE tomorrow, and our main teacher left ages ago, so we've been stuck with cover teachers since November. These videos have really helped me keep up. Thank you.
This is the Best TH-cam channel that teaches science. Lots of credit to the person making these videos. Wish him lots of success in his life. Lets get him to 1 Million Subscribers ASAP, after all that he has done for us.
Thanks, I´m from Spain, but my physics and chemistry lessons are in English, our teacher "explains" in a bare studied English, and tbh I don´t umderstand a thing... Thanks 4 the video!!
omds your saving me you explain it so clearly! do you reckon you would ever do past exam paper walk throughs? as there are some for maths but cant find any for sciences
@@ValyderBB Thank you but a molecule can be diff. elements held together by chemical bonds. He said it at the beginning e.g. carbon dioxide contains carbon and oxygen which are diff. elements but they still count as a molecule and a compound. But thank you for helping! :)
I have been searching the web for this question for 1 hour... Finally, TH-cam suggests THIS video that is SOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOooo helpful! Thanks a lot
Molecules - two or more atoms that are chemically bonded (could be the same elements or different elements Compound - two or more DIFFERENT ELEMENTS the are chemically bonded Now (all compounds are molecules… but not all molecules are compounds ) Eg. Water is molecule and compound… but oxygen (O2) is a molecule but not a compound (Hopefully this helps)
Can elements also be compounds? for example, can oxygen be both a compound and element? I don't really get how all these relate to each other but also differ.
i have a doubt, o2 is also one atom but it doubles to form a molecule then why cant a helium atom double to form a molecule ? pls explain i have an exam
I just wanted to say I’ve recently started watching these videos and they are insanely helpful, especially when revising.
Hey Rhianna thanks for the lovely comment - really happy to hear it! Good luck with all your work! :)

This is so true he tells us about Marxist theory and calls us stupid brags about his son getting 9s until the end of the lesson when he blames us

You just saved my life... My science exam is tomorrow and i FINALLY learned this
Great to hear that Comic Mania, good luck tomorrow!
Is there any chance this is out of date? Or has the syllabus not really changed?
Nah ur good still using these videos
Bro unless u aren't IGCSE or GCSE u need this
The night before my mock binge watching you videos
tahnks so much i litreally stress this question everyday you made it possible for ,e to understand
Currently studying for GCSE. This youtube channel is a life saver :)
How much of the science content do u know
same
Thank you for these videos. I've got my Chemistry GCSE tomorrow, and our main teacher left ages ago, so we've been stuck with cover teachers since November. These videos have really helped me keep up. Thank you.

This video is so informative and will be useful for my tests and i got the full marks in my chemistry test for this video thanks to this channel maker
Well done Ifza that's awesome 🥳 glad we could help!
thank you thank you thank you, you're helping me so so much with my revision. the facts are so easy to transfer to revision cards
Thanks so much really helpful to revise and to take notes. Really simplified which really helps.
I'm russian, and found this videos more understandable than my textbooks. Wish me luck in passing my chemistry exam
these videos are great! please keep it up, they help me so much (also the math vids, they r amazing!)!! keep going
Frfr itz really help
i have a science test and a maths test next week, and these videos have been so helpful, thank you.
super helpful ,especially when revising any thing you dont understand
This is a great video well done great explanation!!! 🎉🎉
I started watching these videos and they helped me in my text.
What did u get??

they are really helpful .
I love chemistry, biology and physics and it’s because of my teachers and you 😂❤
I love your videos so much
Thank u for making such a good video
My chemistry exam is in two days and this just saved me from failing. thx brudda
your lessons are very helpful
thanks this helped me alot
What will make ur videos even better is if u had a few questions at the end other then that it’s amazinggggg
We'll keep that in mind, thanks Aqsa!
thank you! I really need this for revising lol!

Nice and clear. Showing this to my class for reteaching. BIG thanks for the time stamps! I have just subscribed!
Thanks! Glad you're finding it useful 👍
Thank you Cognito! This video was rlly helpful but can you explain why sodium chloride isn't a molecule? I'm still a bit confused.
I think it’s because a molecule are
2 or more atoms of the SAME ELEMENT held together by chemical bonds
@@ValyderBB Thank you but a molecule can be diff. elements held together by chemical bonds. He said it at the beginning e.g. carbon dioxide contains carbon and oxygen which are diff. elements but they still count as a molecule and a compound. But thank you for helping! :)
@@Hanan-xl9km oh rightt, I'm still getting to grips with chemistry and stuff 😅
@@ValyderBB that's ok :) at least you know now
@@Hanan-xl9kma tinyyyyy bit late but it’s both a compound and a molecule 😅
can you please tell what are you trying to say from this point 3:57. I just can't get what are you trying to say
very helpful thx!!!!
So does that mean that any substance that is a compound will also be a molecule? Or are carbon dioxide and water just exceptions?
i think that water and co2 are componds as molecules are atoms and water itself is ot atom
Best video ever
I have been searching the web for this question for 1 hour... Finally, TH-cam suggests THIS video that is SOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOooo helpful! Thanks a lot
this comes in clutch b4 finals always
Love, love your vids. Nice visuals, straight to the point, always highlighting important points. Perfection!
Its a great tutorial video. Thanks to this. Can you also prepare a lecture that describes Direct Interspecies Electron Transfer (DIET).
u r a legend
i have a doubt that how can we identify what is a molecule and what is a compound?
pls pls pls reply as i ve an exam tom
Molecules - two or more atoms that are chemically bonded (could be the same elements or different elements
Compound - two or more DIFFERENT ELEMENTS the are chemically bonded
Now (all compounds are molecules… but not all molecules are compounds )
Eg. Water is molecule and compound… but oxygen (O2) is a molecule but not a compound
(Hopefully this helps)
thx so much for making these they are great for revision
Thanks Ryan, we hope the revision goes well 🤞
Thanks 🎉🎉🎉❤❤
i have one question, so is water a compound or a molecule?? thanks
Both
It’s a molecule and compound
Thanks I like the videos they are helping me please 🙏 can you make some content on Radioactivity and quantum mechanics?
ty this is good stuff
This is hard but a year 8 doing GCSE level video. It’s crazy. REEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEE
Couldn't thank you more
And it help me alot in exam thanks
this was very helpful thank you
can i use these videos for igcse?
I'm using them for IGCSE. Check your textbook and see if it follows it.
Thank you so much!!!! It was really helpful:)
Great to hear it helped Emaan, thanks for letting us know 😊
Hello, Cognito. are you guys going to do A levels, it would be really helpful if you did. Thank you.
Can elements also be compounds? for example, can oxygen be both a compound and element? I don't really get how all these relate to each other but also differ.
do you reckon you would ever do past exam paper walk throughs?
My exam was coming up but this video didn't a fail me
Why don't the atoms in a mixture bond? ty
Quick question: What is the reason that the substances don't react with each other? Like what stops them from doing so?
because some substances have different melting and boiling point than others which makes them a mixture without being chemically bonded
lifesaver🙏☀🌞🌞
i have a doubt, o2 is also one atom but it doubles to form a molecule then why cant a helium atom double to form a molecule ? pls explain i have an exam
Helium is a noble gas, it has 8 electrons in its outer most shell... it cannot react with any other atom/element
@@PrecoolSkillz exactly right! :)
Yea its sooo helpfull im getting like top marks
