I'm a freshman physics/math dual major. Everybody's dream. My important classes are Honors Physics I, Differential Equations, and Multivariable Calculus. Using Halliday, Resnick, and Krane for physics. Stewart's for calculus. It's an engineering school and I want to learn both theory and application. HRK seems cursory, Stewart's is good. I took the 12+ AP courses route in high school. Apparently I've been shortchanged though. I've read Spivak's is the go to for calculus, and afterwards Apostol. What about for physics? I read some of Feynman's lighter stuff and now I am working my way through the Definitive Edition of his Lectures on Physics. I'll be taking Honors Physics II, Intro to Complex Variables, Advanced Calculus, and Foundations of Analysis next semester. I have plenty of time and motivation to learn this stuff. I slacked off far too much in high school, so I've reduced my life to lifting and studying. Is there a better alternative to HRK? Will working through problems from the HRK improve my physical intuition and so on? Is that what I need? Proper route for studying calculus? Some of you gurus need to set me on the right track before it's too late, PLEASE!
