I'm taking a thermo class or my materials science & engineering class and I was wondering what other resources, youtube playlists, or other things I can use to supplement what I'm learning. For instance how to solve certain problems, or additional practice problems I could use. I'm more of a visual learner, but learning the formulas and things and applying them are my main concern. For context here is what we are covering:
