Ok what exactly do you need academic advice on? Everyone takes the same exact classes, if you're having trouble you speak with the faculty; if you're having even more problems or in trouble of failing, you can speak with the dean of academic affairs. I don't see how the number of advisors makes the school such a horrible place. I personally have never even seen who these advisors are so I can't say what they do exactly, but my point being is that I've never had to use them, nor have the vast majority of classmates that I know of.
Yes, my tution is paying their salaries and while I may not be taking advantage of their services I've gotten my money's worth through being well prepared for the boards and licensure exams, the opportunity to work on more advanced cases in conjunction with different specialties, including time at the implant dept and several cases through aesthetics dept. I was able to do do a couple years of research merely because I brought the idea to a faculty on a whim and he went on board immediately. I got to see what all the different specialties are like, was able to do more complex cases in pedo when I decided I wanted to go into that field and eventually matched to a pediatric program. So yes, I do feel like I got a lot at this school, but again these are just my experiences.
On the occasions where I've needed to see a dean for something I have been able to simply walk in and see them if they are available. Yes, that sometimes means waiting 30 or so minutes, but I have never had to wait the 2 to 3 months you talk about.
While you're sick of people defending NYU, I'm equally sick of people bringing down my school. Hell yes I have pride for NYUl, you may hate it, but I've loved my experience here. Of course this maybe due to the fact that I've done well in all classes, boards, clinics, etc and I've simply had no issues with the program and faculty.
Why don't you give specific information about what gives you dissatisfaction with NYU? I can't imagine it's only because there are a limited number of academic advisors available to the school. Again, I can only say the experiences you get are what you put into it. Yes this school will not hold your hand and show you the many things that are available to you but it has been my personal experience that no door has been closed to me when I was interested in doing something.
