at the moment this channel is literally my best kept secret, the only reason I'm not failing miserably. When I graduate I will probably just recommend you left and right like "oh, you have a test? COGNITO!!"

Really helpful! I'm in year 10, and have been using this to revise for me chemistry mock exam. I love how it makes information, that I find hard to understand in a textbook, easier to comprehend! Will definitely recommend this to anybody who needs revision!

This is so useful, thank you. Would you ever consider doing similar videos but about maths?

This is so very useful, thank you. I was studying for the next standard during this lockdown period in our nation during the current situation of COVID19. Would you consider doing similar videos about space science and quantum physics?
Thanks.

Can we use MgO+Na that gives mg +NaO
So we get mg from mg oxide and also Na is more reactive than magnesium
Please answer

I feel betrayed by cognito because now I cant complete more than 2 questions then the website tells me " you have reached the daily limit".. I still love cognito and will cherish it but that made me disappointed and I'm afraid I can't keep my grades up
