I'm considering a masters in physics because I'm interested in possibly pursuing a Ph.D. there, but never got beyond 200-level in undergrad. The local university offers a physics MS that's basically a rebranding of their undergrad core, but at night to cater to working adults. It'd be cheaper to just take the undergrad classes, but that just doesn't fit into life, so I'm willing to pay for the privilege of being able to take them at night. (A Ph.D. program may never fit into real life either, but that's a different problem for a different day).
