To whoever narrates this, and the videos on Kreb Cycle, and ETC videos, you do a great job.

Funny how I learned way better by this video than my text book which is written in my native language.

Your voice is so calming, and relaxing which helped me calm down! I had all kinds of panic attack before finals 😭❤️ Thank you I understood everything! Why is college not teaching us but Khan academy is! Rather pay them! 🙄

This was broken down beautifully, learned all the little details which is crucial. Thankyou !!!!

[lukem]

This is totally helping me rock my weekend homework that the teacher never actually taught us how to do. Thanks!

[Renku]

Khan Academy does a great work. I have proposed them to school boys & girls who really want to learn with a simple & excellent explanation at their own pace which may never happen at usual shools. They have my respect.
