@PhantomVirgo ok, so at CC, i took PHYS 4A: Mechanics. THe next class is PHYS 4B: Electricity and Magnetism. In Davis however, I do get credit for PHYS 9A (classical physics), but the next class, PHYS 9B, is about fluids, waves, and thermo dynamics (which is the equivalent of PHYS 4C at my CC). do you think I should restart at PHYS 9A at davis due to the discontinuity or should I just take PHYS 9B?
