I will not disappoint her .fFinally I managed to enroll with University Of South Africa this year . I am studying Bsc : Biochemistry and Microbiology part time ,but at this stage I am an Electronic Engineer ,I am changing the stream because I have always loved Biology and Chemistry .

  • As a high-school chemistry teacher, when I'm looking for a good video to support a section of the book, and I find one made by CrashCourse, I know my search is probably done. Thanks for making these captivating and informative videos, and I hope you see good fruits for your labor in the next generation of young scholars.

  • You guys seriously need to make a Physics Crash Course. I'm in Germany as a foreign exchange student and I'm learning these two subjects... without ever having learned them before. Your Chemistry courses are life savers. You should help me to keep from drowning in Physics as well. If you please. Actually, math would be really helpful as well.
