I think most of this is a MYOB kind of thing. Who cares what other people do? Does it really effect you that someone walks in an hour late? Or that people complain about the uniform? Or that someone does their nails? The only thing you said that would annoy me is the changing of the schedule, which would I'm sure not fly with many students who have set their schedules around it. Everything else is really on your instructors. They're not idiots. They know you can find things on the Internet. If it was a big deal to them they would change the assignment. It's up to them to enforce their rules. Same as an employer. Students putting themselves at risk have no leg to stand on if they get in trouble. It's not any of my business, doesn't affect how well I do on exams.
I complain about the uniform. Our school thought the women's scrubs were too risquÃ©, so we all wear men's/unisex, which you can imagine fits terribly on many. And our scrubs are teal, so some of the men in our class have voiced their disdain. I don't think complaining about something you're forced to wear means you're not proud of your school. That's ridiculous.
Also, I'm one of those people that search the web in class. I don't learn well in the lecture. I do better listening to the voice recordings at home with the book in front of me. Ive consistently scored in the 88-92% on exams. Again, what is what I do on my laptop a concern to you? The person that asks stupid questions just humiliates themselves, why do you even give it a second thought?
Nursing school is already stressful. I really don't see why anyone would put any time or energy into what other people do.
