    Hi Cognito! I wanted to say thank you so much for these videos! Your physics, Biology, Maths, and Chemistry helped me with my year 9 exams, you guys deserve the 100K which is just 2K away! You guys put so much effort in your videos moreover how you explain it so it’s understandable and not complicated, not to mention you guys have been producing videos for since 2018! I remember coming across your channel a year ago yet I never decided to watch your channel, I’m so glad I went back and searched your channel because your videos help me so much! Super underrated. ☺️👍

    I'm in year 10, currently revising as many of the topics as I can for my exam this Monday. After hours of scrolling, going through various videos, asking my Teach' for help, going to sites to learn the various methods of learning simple interests...
    ...I find a video that explained everything that should normally take me about 20-30 minutes to learn in 4minuets. I'm so glad I was able to find your channel. The way you speak so concisely and clearly yet so simple makes everything a ton easier!
    Thank you so much for this lesson !!

    Dear Amadeus Carnegie, I'm utterly grateful that I found your channel as my performance in physics and chemistry was very bad before I found you!, Now currently I'm sitting my IGCSE's from India and I have recommend you to all of my friends, and even my teacher finds your videos to be helpful in teaching other classes too. You are one of the best teachers I ever had. we may never meet each other in IRL, but I will keep recommending Cognito to every student. Once again, Thank you for tutoring me, 😊.

    P.S. - Could y'all do more subjects like Economica, etc. ?
