You saved my life in high school chemistry 10+ years ago... now I'm back as a struggling nursing student and you're saving me again. THANK YOU

These videos are the reasons why I pass biology.

As a paramedic instructor, I absolutely loved the videos on the immune system. It allows me to find a creative way to explain this section of pathophysiology and later chapters where infection comes into play. All to make the best 9-11 responders I can.

"humoral.. doesn't mean it's funny" gets me every time

[fuzzball]

Other people donate money and resources but you spend your time and patience making these videos...seriously you are at a whole new level of philanthropy

I did this last year but this time I come here for nostalgia

I have watched all of your immunity videos and have learned more in about an hour than my professor could clearly teach in two weeks.

I have been using these videos for supplementary learning because my college professor does NO sort of visual teaching. It's terrible for me! So after class I come and find the video that correlates with the lecture and I think it's the only reason I might pass my final tomorrow! Thanks.

I'm convinced he has magical powers. Studying for Calculus and a Microbiology test taught by the same dude [who puts everything in (basically) lamens terms]?? Freaking amazing. Thank you so much, good sir. You have helped me and probably countless others pass their classes.

[TheYoungFactor]

I'm convinced the reason these videos are good is that Sal knows the material better than my teachers do.

Still thinking of my lymphos saying "Hey, you're just shady, imma eat you up"

[Kelishax]

I don't know anything about biology but with the help of all these videos am improving myself. pls carry making more video.

[fireblade]
