To add a little more to the above …
If the students change their minds in a year or two either because they don’t want to do medicine any more or they don’t like the undergrad experience or they want to apply out to other med schools regular route or change in family or financial situation they are free to opt out (rarely anyone does though) and transfer some where else. Only expectation from them is to inform the program director at least 2 semesters ahead of their intended date of transition into the med school portion of the current program.
Brown selects more than 90 for it’s program, both ED and RD combined. Final enrollment number will be in 60s, with ORM strength among them as mentioned above.
