I hear ya.
Spent the day frying my brain with all my classes plus an open lab for geology because I missed it last Thursday.
Went to Russian to find the late-night 4 am venture to get my book review done was all for nothing when my professor extended the deadline to 1745 that day, and to put the cherry on top she just now told me that the translations I turned in were for the wrong ones and that I'd need to redo them before class tomorrow.
