But then towards the end of my degree I attended a lot more, and exams becae much easier. Yeah sometimes it’s boring as, but hearing someone explain it can be useful particularly if the text book supports what they say, as opposed to having someone just make their lecture up from the book. If it’s the latter then don’t bother, just read the book if you like! (IMHO anyway)

Sleeping through class is a waste. Why even bother showing up and disrespecting the professor that way? If you want to hand over yearly tuition so you can sleep, by all means. But as classes get harder that is a hard habit to break.
