constant complaining

I'm not sure if this is a generational thing or a gender thing. I'm in an accelerated RN program so about half the class is in their 20s and half in their 30s and 40s (with two guys in their 50s). We have 30 women and 7 men. There are a group of about 10-12 students, all female and all in their 20s, who complain about everything and want everything handed to them on a platter. A few examples:

When we had our med checkoff coming up, there was a school-wide email outage so there was some problems getting the med list to everyone. The checkoff was on a Friday and the Wednesday before, our lab teacher said that people could do the checkoff the following Friday instead if they wanted to. The immediate response was "can we do it on Tuesday?"

Our teachers stopped reviewing tests in class because people argued so much about the questions. They would spend literally 10 minutes arguing about one question.

One teacher planned to have a regular class during finals week. Students complained so much about it, she finally relented and said she would do a review session during the regular class time, starting at 8. The immediate response was "can you start at 9?"

And my favorite is the student who - not once but twice - has asked a teacher to give her credit for a test question she got wrong because she filled in the wrong bubble.

I don't know if it's a generation Y thing or a gender thing, or just the luck of the draw. They have such a sense of entitlement about having everything handed to them. It got so bad that a few of us actually went to one of the teachers to tell her that the complainers don't speak for all of us.

Does anyone else have to deal with this crap?
