Sounds scammy to me if your required to study things that have zero to do with Dentistry?

Unlike other undergraduate models, degrees in law and medicine are not offered at the undergraduate level in the US. Instead, they are completed as professional study after receiving a bachelor’s degree. Neither law nor medical schools require or prefer a specific undergraduate major, although medical schools do have set prerequisite courses that must be taken before enrollment. Undergraduate students who are preparing to attend medical school following their undergraduate careers are known as pre-med.
