Hi, I just finished the Post Bacc Program this year, and I can tell you, it is really helpful. You will have to study (A LOT) if you really want to successes, but it is doable. It is mostly focused on the premed students since we are only a few (this year had the highest number of pre-dental students and we were 15 at the beginning and 9 finished the program), but at the end they differentiate anatomy, we did head and neck instead of pelvis. Pharmacology is really tough so I suggest you to memorize it very well, probably the only one you will have to memorize a bunch of material.
now, talking about if acceptance or not. at least this year, everybody got an interview on february, however, only the ones that had a GPA 3.0 or above received the contingency letter (it is an acceptance letter, with the 3.0 overall contingency). The second semester is the hardest one, so I suggest you to try to get a good gpa in the first semester so you warranty your interview and contingency letter, and can handle a C in pharmacology on sprint.
I am glad I took this program, it gave a good foundation and helped me to identify what works best for me in order to study efficiently. do not procrastinate, you have to study every day because there is a lot of material to be covered. Ohh, do not take a week off. I did that in the first semester and did not bring good results in the next exam, but you will have chance to recover. Do the study guides for the final in Thanksgiving brake, it is the only time you will have to do that.
