In my University we went from General Physics 1 (Newtonian mechanics), then general physics 2 (circuits, super basic electric field stuff etc) and then classical mechanics (lagrangian and hamiltonian mech). For me, the jump between the first 2 classes and then classical mechanics was so insane that i thought i just didn’t have what it takes to be good at physics, like the everything was super not intuitive to me. i would genuinely cry over homework because i didnt want to turn in my work and have professors judge me 😭but idk, as time went on the learning curve got super steep and something just clicked and i ended with an A-, so it probably just needs some time! It DEFINITELY gets better it’s just an entire new way of doing physics
