As a student in the 9th Grade who suffered with my Chemistry basics because of the pandemic during the 2021-22 school session, I am incredibly grateful for these videos! They're divided so well and deliver the information straight away. The diagrams and drawings are also a great help! These are definetly going to save me during this year's mid terms. Not sure if you'll see this, but thank you so much for your work!
<3 (:

In this online classes, chemistry and physics were new subjects to me. I litterally didn't pay attention to the classes so i was struggling for one whole year. After watching this video. I am learning something what I couldn't this
one year

Cognito has helped me so much preparing for science and maths exams. The only reason I am not struggling is because your channel exists. Your videos are amazing quality and easy to understand, whilst also covering a lot of information in a short time. Thank you so much and keep doing what you are doing guys!
