no, i haven't, but i'm always sooo tired for my monday 3-5 tute for human development.... everyone seems to lose energy by that time (we've been there since 9am and have had 2 lots of 2 hour breaks )
then why go? i'd go home and read up on the lecture later on.
but back to the question, yes i have in communications, programming, managing people at work. there some this time that your eylids just drop...
I fall asleep in my Harmony Analysis Lectures all the time.. cant really fall asleep in tutes though... there is only 10 of us and the teacher can see everyone
