Hey Cognito, you probably get comments like this all the time but I just wanted to thank you so much for your videos! A couple of months ago I was predicted a 7 in Biology for my GCSEs, which is really good, but I really wanted to try and get an 8. I started binging your Biology videos (my friend recommended you) and then had a couple of study sessions with her, in which your videos were used for reference. Anyway, long story short, we both ended up getting 9s! Honestly, I was really hoping that I'd brought my grade up to an 8, so the best part of results day for me was scanning down the list of subjects to see what I got for Biology and seeing I'd got my mark up by not one but two grades! Thank you so much (and sorry for the really long comment!)

I'm a college student learning angles again and this channel helps me so much. I've always struggled understanding and learning maths, but this account explains and elaborates things so clearly.

[catwbb]

Thank you. No one has ever explained this and another topic as well as u. This is really going to help me for my test tomorrow!

First and foremost I just wanted to say thank you so much for taking the time to put out free content such as this, truly you're helping a lot of people and for that, you deserve an infinite amount of thank you!!! Your explanations are perfect and easy to understand. Also, a random question as I am just curious do you think you will cover advanced maths? And how long do you think this maths playlist will take? Regardless again just wanted to say thank you.

Great video! Thank you. I left it for my students to watch when I was absent. We generally call them 'co-interior' angles as opposed to 'allied' angles - so that opened up a nice discussion :)

Keep up the good work

So in school they give you this head hurting round about way of finding answers and a long winded explanation that takes up majority of class, and this guy explains it In a digestible way in 5 minutes that's understandable, thank you
