I’m very sorry you had a negative experience with the AO. After reading through others experiences, it seems like folks have either a very negative or very positive experience with WashU admissions. I’ve heard “hard sell” and I’ve heard “super friendly, informative and communicative”. I would like to hear more about your experience via PM if you’d like to disclose. And again, I’m sorry.
Personally, I have mixed feelings about ED. It’s useful for high interest/high information/ready to do those applicants. The downside is that this can preclude price sensitive “doughnut hole” families from going ED. If you’re full pay it is an easy decision. Conversely, if an applicant is lower income, the cost is also well defined. Personally, I do prefer that they don’t use ED to admit less qualified candidates on the basis of their lineage or their ability to hit a baseball 400 feet. That to me is a good thing.
But back to the original questions by the OP. I’m probably the only person here who has entered WashU as a pre-med and completed the gen Chem, bio and organic chemistry sequences. Those classes aren’t picnics. Organic chemistry in particular. But there is a lot of support there (much more than when I attended) and if people have the appropriate level of commitment, they’ll make it through. Five of my closest friends did just fine for themselves. Oncology at Sloan Kettering, medical genetics at Hopkins, Cardiology at a major research hospital in Louisville, psychiatry at Arizona and another in gen Peds. I don’t know anyone who went through the entire pre-health sequence who wanted to be an MD who is not currently an MD. People who can’t cut it do wash out. But more often than that, I think most of the people who drop get exposed to other things that resonate with them more. The curriculum is open enough that people are drawn to things that are better fits for them personally. That was my situation. So I wouldn’t let the “weed out” talk dissuade someone from applying. If someone is good enough to be admitted to WashU and they have a general aptitude for math/science (but they’re not a “star” by any means) then that person is capable of meeting the rigors of the prehealth concentration…provided he/she will put in the work. I can’t speak to the LAC experience, so I won’t even try.
I also am in the rather unique position of have a spouse sitting on the AdCom of a major medical school. Like highly selective undergrad admissions, med school admissions are holistic. Would the same pre-med applicant getting a 3.75 at WashU get a 3.85 at another school because prehealth at another school is slightly less of a grind? It’s entirely possible. Would the AdCom attempt to adjust the GPA across schools? Assuming you’re comparing two repsected institutions (like Harvard vs say Marquette) the answer is (almost always) no. A 3.xx is the same at all schools. BUT, once an applicant hits certain GPA/MCAT thresholds, applicant success depends on everything but GPA/MCAT. Lab/clinical shadowing experience, public health ECs, the ability to articulate why a school + your background will get you to a goal and what that goal is. Evidence the applicant has undertaken a significant degreee of self-reflection, etc. WashU is very good at providing those out of class opportunities to its pre-health students.
Frankly, I don’t think it matters which school someone chooses. There are resume building advantages to going to WashU as a pre-health. There is also some degree of additional rigor and a higher chance than average of a student getting distracted by other academic pursuits. Which can be good or bad. Bad if it’s a true distraction. Good if that distraction means finding your true calling. Where you go to undergrad does not have as much bearing on med school attendance as people generally think and there’s something to be said for going to an instate flagship, keeping undergrad costs down, and using that savings to manage debt/quality of life for the lean residency and fellowship years.
Find the overall school match that’s right for you at the price point you’re willing to pay for that experience.
