    I love your videos they help me so much when revising because I have processing issues and I am a very visual learner. I use your videos for both my math and biology gcse revision, and I’m not joking when I say I literally learned homeostasis from no understanding, because of your video! I could not pass my gcse without you guys! 🎉

I've not only fallen in love with it, but i've also learnt a lot of it in a short time. i'm doing my IGCSEs next year and i know for certain that i'll pass and 50% of the credit is to this channel
