then try to weed them out, get them to quit, or flunk them in an effort to get the number down to equal the number of chairs they have by the start of clinic. I heard that some do this to get extra tuition and rely on the fact that a certain number of students will quit before 3rd year. Can anyone confirm this rumor? Who does this?
I doubt this is true--it seems unethical and a bad plan in general. I don't think that people are automatically expelled if they fail one class, so this weeding out process doesn't seem feasible. I've even heard of dental students repeating classes or an entire year, so people do get second or even third chances. Having said that, it makes sense that certain people would be asked to leave (ex. someone who has failed classes repeatedly or fails the same class(es) over and over again).
The reason that dental schools overadmit, as whodat4life stated above, is because not everyone who is admitted will end up attending. This is the exact same thing that colleges do. They need to overadmit to fill all of their seats.
If for some reason a greater % of people admitted decide to attend the school than expected, you get overenrollment, but I doubt that they would try hard to weed people out in this case. They would have to find some kind of solution, but I'm sure that the school has ways to deal with that. I know a friend whose undergrad institution had that problem one year, and they dealt with it. I'm sure that dental schools would deal with these issues in a professional manner, and that they wouldn't do anything so unethical.
Also, I agree with psychoboylol123, study as hard as you can and this won't be a problem for you. As long as you put in 100% of effort, I'm sure you'll be able to pass all your classes. People in dental school are extremely smart, but chances are if you got in, you're extremely smart too. You just need to put in enough effort and it'll end up being fine.
