I'm a D1, so I'll answer what I can.
1. I really like it here. Between the school, the people, the city, I couldn't imagine being anywhere else. If you are social and outgoing, the large class size is not going to be a problem. You'll always have something to do or someone to do it with. Also, if you need help, the faculty is there for you, but they're not holding your hand. You'll need to seek it out.
2. The plastinates and slices are great for learning more detailed structures. Seeing how we are concerned with the oral cavity and surrounding features, having expert dissections of the entire head and neck is a huge plus. However, for the larger regions and structures, I found cadavers more educational because you can dig around in there and get a great idea of the inner workings of the body.
3. When I observed in the aesthetics clinic, they had traditional x-rays. I believe you learn to do both though, but I can't answer that with 100% confidence.
4. N/A
5. N/A
6. My main exposure to faculty has been through bench lab and observing. In both cases, I found the faculty to be very approachable and helpful. Your row instructor is assigned to 10 people. They are there to help. If you want a second opinion, you can just as easily go to a different instructor. Most (some seem a little "pre-occupied) are willing to help. Also, the administration staff is very helpful. For those that were struggling, the staff set up appointments to talk about how to improve and how to succeed.
7. I was never one to approach professors, so I haven't made an attempt. The professor's do communicate with the class council and listen to our concerns. If we want to change an exam date and it is possible and realistic, they are open to our suggestions. Most of the time, nothing happens due to room unavailability or other circumstances.
8. I don't mind the large class. In undergrad, the average class for some of the science courses was 300+. That's why I'm always kind of surprised to hear people freak out about 250-350 students. Also, with the large and diverse class, I've met a lot of people with different backgrounds. I think that's a huge plus.
9. For some, this was a dream school, for others it was there only option. Some really like and I have to assume some really don't.
Extra: NYUCD implemented a new curriculum to better prepare students for the boards, ideally. We took a combined Anatomy + Biochem (3hrs) midterm and have a combined Anatomy + Biochem + Cell Biology/Genetics final exam (6hrs). It seems that most did quite well on the midterm. Also, next semester, we will have quizzes that will test us on the material we learned this semester and I believe that this will continue each semester. Feelings are mixed. I like it if that means anything.
I think NYU takes a certain type of personality. If you can't handle city life, it won't be for you. If you can't speak up and seek help, it won't be for you. If you aren't outgoing enough to meet new people, it might not be for you. The opportunities are available if you want to pursue them.
I think that's it.
