although i've never heard of barry university, i'm sure their 2 year combined post bacc & masters program is challenging. but for the most part, it is my opinion that the majority of post-baccs inflate grades.
e.g., i had three pre-med friends at college who studied hard but got mostly Bs and Cs. they struck-out applying to med school so they all did a post-bacc at different programs. nobody had to break a sweat and the lowest GPA between the three of them was 3.8-something.
