Hi, I am a senior in high school and I want to learn more about thermodynamics and physics in general. Unfortunately, I don't have anything available at my high school. I am trying to find online courses but I honestly don't know where to look at because some of the courses I've seen seem too basic and the others too advanced. I've looked at khan academy's website and I find their physics program kind of basic. Can you reccomend me any online course? Thanks for the help!
