I had a 2.9 science GPA and 3.25 cumulative GPA in undergrad. I hadn't taken physiology, histology, pharm, anatomy, and a couple of the other classes before, and I passed. I didn't get into med school the first time I applied, thus the post-bacc. Careful with comparing stats with other people on SDN though. It can turn into a toxic black hole.
Yeah, sad to hear that so many dental students didn't make it... I don't think comparing the matriculation statistics for dental vs medical students means much though. If both students are taking the same courses, then that means LECOM holds their dental students to the same standards as their medical students. I want to assume dentists are just as capable as medical doctors. To expect more leniency for dental students implies otherwise.
I do agree with Floss Boss that some of the courses might be irrelevant for dental students. But again, the standards thing. If medical students can do it, so can dental right? I don't know much about dental requirements, but from what I've read, it sounds like post-bacc is more of a chance to show LECOM that you are ready for their dental program rather than learning things that pertain to dentistry. Most people are taking the post-bacc because their grades/scores weren't good enough to get in the traditional way or because they're changing careers. This program is a pretty good way to show LECOM that you can do it. And nothing wrong with knowing a little more about the human body, might come in handy someday.
About the whole head/pelvis thing in anatomy... Yes, dental students learn head while medical students learn pelvis. Yes, head is definitely harder. But if the rest of post-bacc is irrelevant for dental, I would think then, that the head is the most relevant part of the program. Heck, I'm sure dentists actually know more about the head than the average doctor. Because they need to. The fact that dental students have to do head shouldn't be a point to complain about, but rather a point of necessity and maybe even pride. It's like wanting to be an orthopedic surgeon and complaining that you have to look at more X-rays than a primary care doctor does. You're going to be looking at more heads, might as well get a head start.
I've seen a lot of people work hard and still not get in. So it's not a matter of putting effort in, there must be some other factor(s). I don't know what though. Study hard and study smart? As for not having sufficient undergrad prep, dental/medical schools won't make their classes easier just because someone did an "easier" major or school. Just gotta suck it up and work harder.
As for the lack of support for the dental application, that really sucks. Maybe the one student that did get in is keeping an eye on this thread and can help you? Or perhaps even older post-bacc dental students, sounds like you talked to a couple of them already.
