I'm taking Physics 121 with an instructor that I personally find confusing. Nothing in the lectures nor explanations during office hours get through to me at all. Our assigned text is "Physics, Volume 1 - Resnick, Halliday, Krane." I want to get a solid foundation of the material (beginning kinematics and dynamics: motion, projectiles, vectors, forces, etc.) that will carry through with me for the rest of the 12x physics sequence, and beyond. Is that possible from reading and taking notes from the text alone or should I drop the class and try with a different instructor? Thank you!
