hey cognito!! i got my o'level results a few days back and i scored A*s in all sciences! i couldn't afford tuitions for any subjects and at first i was really scared that i wouldn't be able to get good grades. everyone else in my class got tuitions. your videos were the only thing that helped me. it's such a great thing that you've uploaded all of this for free. everyone else only cares about making money. ur the besttttt

I have to say thank you soooo much😭 For some reasons, I didn't have any lessons in year 8 and 9, I can’t catch up any of the subjects, but your videos helped me a lot, really. At first, I got all the subject 3-4, but I’m catching up because of your video, I’ve just done mocks, and got my result back. I got both 9 in chemistry and physics, and both 8 in maths and biology. Really thank you very much, without your video, I’m absolutely still struggle about science and maths. You saved my life, thank you🥹😭 I hope you can see my comment.✨

Being a student over the course of 11+ years filled with numerous experiences, transitions, interactions and in particular the knowledge gained whether it was related to academics or perhaps the practical world around me, has been a nice way to spend these several years. My hard work throughout these 11+ years has been apparent through my records whether it was just a brief document of my grade sheet, work experience/summer workshops feedback and currently my GCSE's predicted grades. Fortunately, my experiences of transitioning through 3 different schools in different cities and specifically different countries have prepared me to become organized and efficient.Furthermore, these 11+ years has shaped me to become dedicated towards my academics and essential life skills.Personally, I have been

hey, 9-1 papers mean papers that can be given a grade between 9 and 1, which is the new grading system for gcse papers instead of the letter one (eg A*). you can definitely use these as past papers to revise :)

Do you plan on uploading more lessons to KZbin?

[@emmarobson-x7m]

hey Cognito, this question is not of relevance to the video but I wanted to reply to your latest one so you had a better chance of seeing it. I have been kind of confused about redox reactions specifically determining which element gains and which one looses electrons. In my example I took bromine reacting with a potassium iodide solution and I balanced the equation and wrote the individual ionic equations, cancelling out potassium because it is a spectator ion. I then did Br2 ---- 2Br and I know that the diatomic molecules have a neutral charge and bromine has a negative charge so its like going from 0 ---- -2 which is subtracting 2 but apparently its not loosing two electrons its gaining two, because in the answer the 2e is written on the reactant side which means its gaining and being reduced, How?
