The responses above highlight common misconceptions and truths regarding BA/MD programs. I am currently in medical school in a BA/MD program.
From my experience, there is a mix of jealousy and difference of opinion and ignorance which leads to some of the misconceptions regarding these programs; and these misconceptions are:
1) BA/MD applicants don't match as well - not sure where "lalalala" got that one from
- At my school and from students I know others, a decent number of the top AOA candidates entered in as BA/MD students
- In addition, everyone in my particular program had a 1500+ on their SAT, several got into Harvard, Yale, and UPENN (including myself) and we all turned them down
2) You cannot diversify your interests and be "well-rounded"
- Go to a 7- and not 6-year program and most programs will encourage you to study abroad, pick a humanities major, etc. if that is what you are into
3) The programs are decreasing in number per year (as per Law2Doc)
- Last time I checked, they had increased nearly 600% since the late 90's in terms of the number of students accepted directly into medical school out of high school
The good things about 7-year programs
1) You don't have to deal with gaming - the art of applying, bull****ing, interviewing, and dealing with the capricious nature of medical school admissions
2) You have the freedom to learn what you want in undergrad
- If anything, you are more free to take risks, study abroad, take random classes because you are already in medical school
3) You distinguish yourself from the "premedical students"
- At my program, I was taking graduate courses in my freshmen year and was already doing research at the NIH
- People are impressed; generally the stats of a BA/MD student kill any other applicant to even Ivy league institutions
Advice:
1) Don't go to a state BA/MD program or a 6-year, those are in decline and are restrictive of what you can do.
2) Go to a private 7- or 8-year BA/MD program that lets you major in whatever and study abroad
3) Make sure you explore programs that provide scholarships.
- My program carries with it substantial scholarship money which again makes it better than the typical "premedical student" applicant route
4) Don't go to a BA/MD program unless you are committed, hard-working, self-motivated, driven and the like
- It is not an option for the lazy to duck out of the MCATs, it is something that is a blessing those who know they want to be a physician but don't want to put up with medical school admissions garbage.
Finally, it is true that most BA/MD students if they went through regular undergrad and then applied could probably go to a better medical school. But, I have saved an inordinate amount of stress, money, wasted time, and grief by not having to apply to medical school. I have had the chance to take classes I never would have as a premed for fear of getting a bad grade (Ancient Greek, Fiction Writing, graduate courses in Forensic Pathology, Tropical Medicine, etc.).
In short, if you fit the personality and know you are suited for medicine and can commit now, go for it.
