it's been a super long time since i logged on here, but it's a good thing i did because i'm in ms. a's class but have a bit more info.
The monthlong derm elective at Ben Taub is a cinch - i haven't taken it but i know many who have, and from what i understand you're only working 3 or 4 days per week and of the rest, some are half days to my understanding. keep in mind that all baylor clinical students have thursday afternoons "off" for class/preceptor, so no one will miss you thurs after 1:00 no matter what you're on.
the general radiology elective at Ben Taub is also pretty cush (as cush as you want it to be, as with any radi-holiday rotation) but very difficult to get as it fills up super fast. doing radiology at a different hospital will NOT be a cush experience, an unfortunate few in our class have suffered through that.
some students here take a monthlong "clinical ethics" elective, to fulfull requirements for the "ethics track," which i hear is also super cush - lots of short days and such. not sure if visiting students can take it, but definitely worth looking into.
those are the cushies that come to mind. i'm sure there are random cush experiences here and there (had a friend who did a month of pedi allergy/immunology which seemed pretty chill), but i can't really speak to those. of course if you haven't already, you can also check out UT-houston opportunities. good luck!
