nobody I've ever came across on this planet explains stuff as simply as you do. I can understand challenging topics so well and I can feel the pieces of the puzzle come together perfectly, and i'm not even a gcse student, Thank you so much!!!

I have been watching your biology and chemistry videos for a year now I just switched options and missed a whole year of chemistry and this helped me with the topics I missed also the biology videos really help me analyse and study before my exam

[CloudysWRLD]

Basically what the video said is teachers dont pick entertaining videos only boring videos.

[augustinemendez]

Even those who don't like science will love it after watching these videos
