I am at UNLV, just made it through my first semester. It was tough, much, much tougher than undergrad, twice the work load, in class twice the hours, plus many extra hrs doing wax ups and stuff like that. If you want to be top of your class here generally you need to spend at minimum 3 or 4 hrs studying per night, if you just want to pass, cut that time in half. Now every night is not that many hrs but if you average it out. Every school is not created equal, obviously AZ and a few other schools are not that bad from hearing from other guys on this forum. I do know a second year who is a hygienist who works saturday mornings. Second year here gets a little easier from what they are saying. But every school is so different.
