I have a teacher who does not teach 😂 he leaves everything to us and expects us to succeed in his course. This really helped me in understanding this concept that took me a long time to try to figure out on my own. I have a test tomorrow and I think I'm screwed but this helped me at least a bit to boost up my mark 😂👏🏼

I started using Kahn when I was in 7th grade math before anyone really knew what it was. Now I’m starting my sophomore year of college with a rigorous 6 week biology course. I love these videos and how they’re made so simply

this is awesome!!! Khan academy is a way better method of learning than actually goin to school. I have my biology exam tomorrow and just a few minutes before i had no clue what isotonic and hypertonic and everything meant because my teacher confused me. After watching this vid everything is clear and i'm pretty sure i'm going to nail the tonicity questions in the exam.
