dental school test files?
I'm a pre-dental student, and I'm shadowing dentists right now. One of my dentists was telling me about how he used "test files" to get through all the tests of dental school, and that his university didn't condone them, but they also didn't do anything to prevent test files. I was wondering, are test files a common thing in dental school, where first and second year students purchase old tests from upperclassmen and use them to study? Thanks!
