I am just finishing up my first physics course this semester (as a physics major). Although there did seem to be a lot to soak up this semester, I didn't feel like it was too bad. I am just curious though, is there a resource that has a list or other type of reference material that shows you what formulas and such that you need to memorize for this and future courses in physics? I memorized everything from this semester even though our professor gave us the option of reference cheat sheets. However, I know as time goes on, trying to memorize it all will be impractical, but would like to know what I should be memorizing and what can just be referenced back to as necessary?
