I am a biology major but was losing my interest recently in school and my major. I came here through recommendations last night and watched almost all of your videos since. Each video reminded me why I chose biology in the first place and got me excited again. Your excited voice and sense of humor got my hearts beating with my hopes and dreams once more. I cannot thank you enough. How did I forget how much I loved biology? Thank you, thank you. XOXO

As 34-year-old college sophomore, I learn more from these videos than I do reading the text provided by school.
