I transferred.
You need to check the schools policies as this is independent for each individual school. There is usually a "transfer" tab or button, and/or it is covered in the FAQs or handbook.
Some schools outright do not take transfers, regardless of degree or reason.
Some schools take only people pursuing the same degree (ie DO-DO or MD-MD).
There are some schools that do DO-MD or MD-DO. These are less common, but exist.
In addition to the school ALLOWING for transfers
- there must be space in the class to which you'd be transferring
- you must be in good standing with recommendations from current institution
- everything must have been past on first attempt
- boards must be completed early enough to receive scores back to submit in time to be evaluated for transfer
- typically this means you score AT LEAST the mean on boards, but not sure with new P/F
- typically must have AT LEAST the mean for MCAT (yes this still matters in this case)
- while this is irrelevant for 3rd year transfers, transferring between 1st/2nd year (even less common) coursework must be considered equivalent for year-to-year as to ensure you don't miss anything in M2 as some schools teach things in different order.
---- this list, even if all are check, doesn't mean it's a go. Your situation must dictate as well. It sounds like yours might, but that's up to the dean and admissions at where you'd be trying to transfer.
Basically, if the school doesn't take transfers, then you can't. If they do, the above list is a lot of what is generally considered for it.
In general, it's possible, but it is not very likely.
