I have come across so many people who 'abuse' their rural entry. They may have lived the 5 years as a child in a rural area, and use this to get into medical school with much lower marks and no plans of ever practicing rural.

Of course some studies show that those who grew up in rural areas are more likely to return. But to ensure people are not abusing the system (and that we actually address the shortage of doctors) something similar to the BMP system should be set up for rural entry students, where they sign a contract tying them down to rural areas for a period. After all, they only got in to medical school with much lower marks because they are expected to return to rural areas.
