Does anyone have any suggestions between 18.04, 18.06, 18.075, 18.085, 18.086, 18.100, 18.311, and 18.703, for someone much more into coding than to math these days? I really have little sense if any of this is going to be terribly useful to me, and AFAIK course 18 doesn't have an underground guide equivalent? *shrug* I guess group theory or something could be cool...
