    repetition is the best way to learn. I enjoyed this video, thank you.

      +myra B Actually, the best way to learn varies from person to person. It may work for you, but for most people the best way to learn is to actively question and understand the concept. If you are trying to learn facts, then yes, repetition is good. :)

    You are a legend, I cant believe you explained this concept better in 20 minutes than my lecturers could in 3 hours. :D Love it keep the good work up man. Thank you very very much.

    Dude please give a lecture about advanced immunology - B and TCR formation, complement system, cytokines, etc. I am studying medicine and you normally have enough substance to achieve greater levels of education but the immunology is under-developed :(

    i had an incredible professor for my immunology course, who happens to be one of the top faculties in my university. Your lecture on the Helper T cells was perfect. I never thought that I could compare anybody to my immunology professor, but you are just as good. You have talent for teaching that very few people have and this is why you are so successful.

    I am a Ph.D. student in Biochemistry/Molecular Cancer Biology, recently checking some interesting vids here specifically for interferon-gamma/cytokines induced immunity invasion which triggered tumorigenesis and happens to run into your video, very neat and easily illustrated (since immunology is not my background lol) keep up the great work and probably will check out more later!
