What is the point of studying E&M if literally all of it is described with these 4 equations? All you need to do is unwrap how to apply them and the physical interpretations of them, all of which are covered in undergrad E+M classes, and you're good to go.

Is that right?

fuck no.
nature is complicated. knowing a model for how it works doesn't imply you understand the consequences of the model in all circumstances.

yes, E&M is a math class in disguise. it filters people who can't calculate the field around a square solenoid.

there are precious few symmetries that admit analytic solution.
big-penis engineers usually have to resort to numerics.

Is there anything that crazy to learn about in E+M past Maxwell's equations though?

physics studies models, and models are only valid within certain ranges.
maxwell's equations are an excellent model, but they are not an entirely complete description of what nature is doing, and fail when pushed too far.
for instance, classical EM can't explain the structure of the atom.
if you want an even better model (that is even harder to apply), you go to QED when it becomes important.
the sooner you appreciate that physicists study models of the natural world instead of absolute truth, the sooner you become a good physicist that knows when to apply a particular model and why.
