Today marks the end of my gcses. I just wanted to come back here and say thank you guys so much for being there for me. You have helped me so much throughout these past two years since I found your channel and I have eagerly watched your videos and used the resources you provided everyone to aid my revision and it has made doing my science exams much easier. I was normally someone who struggled with science for a lot of my secondary life, and finding you guys has changed that. Today I'm proud to say its my last day as a Year 11 student and I have just completed my last gcse exam. From the bottom of my heart, thank you for being there for me and other students too. I couldn't even begin to tell you the massive impact you had on me and other students. I wish everyone here who is doing gcses or even A Levels the best of luck next year! Goodbye. I will return here on results day to let you guys know what I got :)
Congratulations! 🎉 Thank you so much for this message, we really appreciate it and we're glad to have been able to help you on the journey through your G.C.S.E's. Best of luck with your results and A-levels next year! 😊
Thanks to Cognito I got 3 9s in sciences and a 9 in maths. I can't put into words how grateful I am for your videos, you've helped me and countless others
Dear Cognito, I know this is a bit late but I only got my GCSEs yesterday. I would like to thank you so much for making these videos, you seriously helped so many people. I managed to get all 9s in triple science thanks to you and I am so grateful. Keep up the amazing work!! Thank you so much once again
Heading into my final year of secondary, and studying for my GCSE’s. You’ve helped me so much and I thank you! You’ve genuinely taught me more (Thanks to your website too) than my teacher has in a whole year. I’ll be back to update this comment when I’m done with my GCSE’s! Thank you again.
I discovered this channel back when I started my IGCSEs, and my words cannot describe how much this channel has helped me. Last year, went from a D- in my first semester to an A in my Biology finals thanks to this channel. Thank you so much :)
Summary: Larger organisms require speciallised organs like transport systems and exchange surfaces (like villi and alveoli) as they have lower surface area to volume ratio (surface area deceases as the size of organisms increases) and therefore they can’t rely only on diffusion. Smaller organisms (mostly unicellular) don’t have and don’t need speciallised organs as they have larger surface area to volume ratio and so they can totally rely on diffusion for the transport of molecules. Note: surface area to volume ratio decreases as the organism gets larger and so when the surface area to volume ratio decreases the reliance of diffusion of the organism too decreases and they are more likely to develop a specialized organ.
I would like to say thank you so much for all you have done, I went from grade 4s and 5 at the end of year 9, to a grade 8-9 at the end of year 10 ppes, thank you so much, I hope I can do well next year too
Thank you sir for helping me a lot with studies. Today is a crazy day cause I needed to revise and thanks to you, I’m going to my exam completely understanding of everything, thank you for your help and God be with you. Much love ❤️
I was about to drop biology off, but then I found this website. After learning here for about 1 week, I've become top of my class and get really interested in biology and want to pursue career in healthcare fields. I just want to thank you so much for this because it's helped me to much.
I remember watching this for past 2 years for my high school examination in March22, never knew I could get the best result I ever had thanks to this channel. Now I'm entering university, wish me luck!
Hey man, I’m just commenting to say that my IGCSEs results came out and I got an A* in coordinated science (all 3 combined) Thank you for all the videos!
Sir u hv helped me pass my test with last minute studying, I wish you and your family and family the best of the best. Thank you so much for your dedication, Please continue contributing to the betterment of us student.
I just got my results for my gcses I got an A in physics and a B in chemistry. I am so happy and I honestly dont think I could have done that without you!!!!
Thank you so much this might be another one of those comments but on the bus to school before my maths gcse which I was already under prepared for I watched some of your maths videos I can say with confidence that you have helped me push my grades way up. Honestly I learnt more on that bus ride that I have learnt in class.
Hello, I'm currently in year 9 and have mocks in February and igcses in may (I'm homeschooled), I just wanted to say THANK YOU SO MUCH for creating this channel and taking your time to make these amazing videos!
hey! just to let you know, your website is really really helpful. I've been using it ever since it launched and I can see the improvement in my confidence in all three sciences. Appreciate your efforts 💯💯
Hi cognito, I’ve just received my gcse results and got a 99 for science. I’m so happy and it’s all thanks to ur very helpful and educational videos that made my science journey easier for me. ❤️❤️💓💓💗💗💕💘💝
I know that u have heard this a lot but I too want to thank from my part that you truly are a life saver. Whoever gave the idea of making this channel bless them & the people who are doing hardwork in maintaing this channel. No words can express the gratitude. Next year I have my gcse exams but I am worried how will I do in other subjects in A levels without your channel's support T-T. Just a request if u can do make A level videos too. Perhaps on a new channel... Anyways thank you for the great to the point content you provide. May your channel grow even more!
Just wanna say I really thank you for the explaining about this subject , even thought I’m study at school in village ( use my capital language = indonesian ) , but because you I can improve my English especially in listening + improve my brain about chemistry and biology 😅
Hi, I don't often comment, but thank you so much for all the help and explanation for all the sciences, especially Biology. It's been amazing knowing that I can rely on every video being relevant and understandable, as well as the beautiful animations. Thank you Cognito, it's truly the end of an era 💜
Your channel and website is really helping me to understand science. Your videos are really interesting and you explain everything clearly (a lot of the time, better than my teachers). Thank you so much!
thanks so much ur voice is so calm and relaxing which helps me concentrate i was able to achieve grades 7s with 1 - 2 days with cognito rather than through my teacher in years (was at a grade 5)
so so helpful for iGCSE students as well your platform has been extremely helpful and im so grateful for these videos. it really helps me for my exams! thank you
These videos are so helpful! Just curious when the next one is coming as it's been 4 months now. Also, you've mentioned that there will be new videos based on trigonometry in GCSE Maths, and are those still going to come, they'd be super helpful for me! Thanks for these great educating videos, they've helped we improve greatly in understanding the subjects much better!
your videos helped so much while studying for my igcses, im so happy with the grades i got and its thanks to this channel! im moving on to A level now and i was wondering, are you ever planning on making videos for A level?
I just wanted to thank you for the help you gave me on my GCSEs, I hope my efforts paid off and paired with your amazing videos I’m hoping for good grades, for the entire team at cognito I thank you for your help and amazing videos.
I’m in 9th grade right now advanced level, I’m just starting to watch your video my finals are in one week or 2 my biology exam is the third one so I don’t have a lot of time and my clas exam is gonna be this week I didn’t bad in thr past 2 so I hope I can understand fast!
Thank you for creating and producing your videos. They are a massive help to me, especially for my learning style: simple and concise. I am doing my GCSE’s this year and I am very grateful. Also, just thinking ahead, I was wondering if you are planning on ever making A level content videos as they would be a great aid in mine and I’m sure many other student’s learning journeys. Overall, I just wanted to give thanks for all the effort you put into your videos. 🎉
hey!!!! you really helped me for my biology exam. I got a 4 which is what I was aiming for since i got a U (but i think that it was not my fault as the diagrams were printed badly) last year, Thanks!!!
You are literally a life SAVER!!! thank you sooooooo much for EVERYTHING... the physics, Chemistry, math and biology. I just wanted to ask you, will you still make videos about genetic modification and use of microorganisms in production of food such as yogurt and wine?
Your guys videos has helped me immensely for my gcse's , could you guys make videos like these for common A levels like maths and the sciences,thankyou for all the help you guys have given.
Hello I am actually studying IGCSE and I want to thank for your effort, you'r such a great guy! I want to ask why is the CHEMISTRY exam Qs by Topic are not working ?
These videos are really helpful, thank you :) Could you please do one one the nitrogen cycle ? Those of us doing OCR Gateway would really, really appreciate it.
Hi there, I am a science teacher and I think you channel is great. I always recommend it to my students. I really love the layout of your presentations. I am wondering, would you mind telling me what app you use to make your presentations? Best wishes, Ciara
Thanks for the kind comment! This one was made using sketchbook on the iPad, and iMovie - in a bit of an unintuitive process. These days we use Adobe after effects :)
I used the best website there is for science and it was your's cognito, So can u please add A-level biology videos made by u. I'm sure it would help u more than it will help me.
bit of a late thankyou, but your website with the videos and questions saved me during gcses and now im studying biology for an a level. You taught me more then anything ive ever learnt at school. tysm
thank you so much for creating these videos and also the website which are so helpful and helped me during my gcse revision thanks to you i got a 9-8 in combined science and im so happy you guys are amazing💗
hope you dont mind me pointing out, there's a slight mistake in the topic names for edexcel higher physics: topic 6 is named radioactivity which is correct, but then topic 7 is also named radioactivity when it should be astronomy. as ive already said, the website is incredible thank you so much🌟🌟
Heyy!! Your videos are very catchy and easy to follow along. Especially the website’s amazing, I’m being able to judge my progressions and being able to work more on the weaker one. I’d like to make a request to you to pls cover up the computer science topics for the O- Levels as well since there aren’t much content creators for it like for physics, chemistry etc.. Hope you’ll do it soon, and thank you once again
Heyy I really love your website... I would really appreciate it if you could post topic questions for Edexcel As level, chemistry, biology, physics; 21 of my friends are willing and would be glad to engage in your website too!! Thanks
