As someone who is a few years into their CS career, I wish I knew where to 'restart' learning sciences (bio,chm,phy). I am quickly overwhelmed by the plethora of resources people throw at you when you ask that question (There's Khan Academy, there's OCW, there's actual textbooks, coursera, pop science etc)...
Anyone manage to at least start? If so, where? I mostly forgot my university level science courses.
