Hi Schoolhouse team, I love the certification system for math. Please expand it to include Khan Academy's new mastery-enabled science courses. In particular, high school physics and bio; AP Physics, Chem, Bio; Environment, Micro, Macro, CS Principles; Computers and the Internet; and even World History Project 1750 and Origins. are well suited. But of all these, the science courses are best suited for the current certification mechanism.
There is a way for getting certified in high school science already: Experimental honorary certification. But I'd love to see an Experimental math-style regular certification for at least high school physics, hs biology, and maybe AP Physics, AP Chem, etc. I'm looking forward to tutoring science, but I'd like to submit something more than a mere self-attestation of my experience with the subject. I enjoy doing the math certification videos, and I'd love to do it for science too!
