I had a friend take their prgm, it is suppose to be rigorous. I know they got several, he took the one where you take all the 1st year courses with the dental students and if you hit proficiency marks in all the courses (B or above) you are pretty much a lock for acceptance.
Just as a side note, i did the masters prgm for pre-professionals at UMDNJ which is one you should also look at, although i don't know where you live. My science GPA was on the low end (3.1), but i took the prgm which allows you to take 2 classes with the dental students as well as some graduate level courses and 1 research rotation. Afterwards, i got accepted to every school i applied too, as opposed to the first time where i did not get accepted anywhere. This shows me the prgm works.
GOOD HUNTING!
