What are your general comments?
Overall, the program is good. PBL is definitely something different and it is not for everyone. I don't know how well they do on board exam but with no lectures, more effort is required to study for board exams. I also got the impression that they don't have high specialty rate. If you want to specialize, you should consider elsewhere. However, they do have great graduate program; consider applying after your DDS degree. Also, during your Mock PBL session, don't "over participate", let others speak as well, try to listen/understand before speaking nonsense, be professional after all you are a soon-to-be dentist
