3:09 That got a chuckle out of me. It's these little diagrams and facts that really make me appreciate channels like these. Thank you, Cognito.

been watching this playlist since yesterday and i could say that this is the best physics course i've ever took in my life. i have no obligation to pass GCSE test but you really answer all of my curiosity about physics. Thank you, Love from Indonesia

Even though I get most of the stuff from school watching your videos is still a blast because I get more information and understand the topics even better. This is going to help me so much in my board exams. Thank you so much Congito and amazing work !!!

thank you sooo much for these videos, my physics teacher teaches the content terribly and mostly rambles about other stuff, you are basically saving my gcses while i binge watch your videos

I think you didn't elaborate on circuit breakers enough- you will miss marks if you just say they 'stop the circuit', you have to say they act as automatic switches. Please go in depth more in these videos and thank you

[GabstheGamerYT]

could you explain what exactly grounding is and the process and science behind it?

[iestynjones]

Great video. Thank you. Can I ask you what software you use to produce this?

[Army-gguw]

I always forgot about physics unless it's exam day thanks for the last day help

Anyone else watching this for online school?

Plzz make a video on calculation of energy consumed and also power rating appliances

I especially like all your videos... Just wanted some videos on Information Communications Technology. It was better if you add some videos on them. By the way, can i get to know from which website or software are you making these whiteboard videos
