Well I am a 4th year at Marquette and I will give you a truthful summary.
Students: The students and their personalities are different from class to class. For the most part, the students here are very nice and easy to get along with. There has never been a time where I have not been able to approach any student and ask a question or get some help. We are a fun group!
Faculty: I do not think the faculty are too hard on the students, or are they unreasonable with their expectations from us in clinic or lectures. There are a few that I could do without but there are students love them...and the other way around. You just have to be open minded with it all.
The school: I have not heard anything about what WiscoRDH is saying about the students lacking technical skills. As a matter of fact, the school does a great job at getting us into the clinic in our first years, and by the time we are ready to do operative on patients the end of our 2nd year, we are not only good with our hands, but we are comfortable with working on a real patient. We start making dentures for patients in the clinic the summer of your 1st year, and there are a great deal of exams and competencies that you must pass in order to advance from year to year.
The main thing to consider is that everyone will have different opinions about things...so don't just hear a few things about a program and base judgment on it until you find out for yourself. You just have to visit the schools you are interested in and see for yourself. I have never heard of anyone that has come to visit Marquette that has not been impressed with our faculty, students, and facilities. I don't regret my decision to come to school here one bit! Hope this helps, and hit me up if you have any other questions.
