I swear everybody I know tried to make me understand this but no one could you only took 6 minutes and I memorise every word and understand it too. Thank cognito thank you very much!

this is the best revision guide i have ever seen yk absolutely amazing

Thank you for this video. I loved it. The textbook is so complicated, the video was much easier to understand. I understood the concept very well. I am pretty sure that you will become popular very quickly.

Bro explained everything my teacher struggled to teach for a whole week in a time period of 6 minutes. That, indeed, is an absolutely astonishing feat.

It took us guys one months of one hour classes twice a week to finish this chapter in class! But, i don't believe what superpower this guy has that he finishes these topics in 5 minutes!

cognito why are the eggs coquette

omg ty this so useful all other videos were either confusing or just straight up worng

You are growing very fast. By the time it is May you will be on 50K subs.
