Howdy! First of all, congrats on getting into nine different schools, and double congrats on your admission to both Brown and JHU. Both of these are awesome schools and attending either one (and doing well at them) would ensure admission into a wide variety of medical schools. That being said, you shouldn’t choose an undergrad with medical school primarily in mind since undergrad is supposed to be its own stand-alone experience, and at the end of the day students enter medical schools from the full gamut of undergrad programs (public, private, liberal arts, etc.) Based on what you what you want to study (Neuro and Public Health), I personally would choose Hopkins since these truly are some of the best programs the school has to offer. I recently posted in a thread discussing the benefits of studying Neuro with someone considering Cornell and Hopkins, and that discussion addresses many of the same things I would say to you: http://talk.collegeconfidential.com/johns-hopkins-university/1878658-johns-hopkins-vs-cornell.html#latest
Additionally, the public health program at Hopkins (both at an undergraduate and graduate level) is considered one of the best in the world (http://www.usnews.com/education/best-global-universities/social-sciences-public-health). Hopkins has the #1 graduate public health program (http://grad-schools.usnews.rankingsandreviews.com/best-graduate-schools/top-health-schools/public-health-rankings) and as an undergrad Public Health major you take many of your classes at the graduate school (at least 15 credits). But beyond just telling you USN’s opinion that Hopkins is so well-regarded, I can even tell you why! As with why the Neuro program is so great at Hopkins, so is this why the School of Public Health is so well-regarded… amazing faculty, flexible programs, support and…research! Hopkins is THE research giant, outspending every other school by a landslide for the last 35 years, and much of this money is in healthcare, biological sciences and public health. JHU students have so many opportunities to do research (which is required for Neuro, encouraged for Public Health, and the Public Health does require an Applied Experience http://krieger.jhu.edu/publichealth/academics/), and participating in research is essential for a quality undergrad science experience (read the Cornell discussion for my elaboration on this). Secondly, Baltimore is a big city with a long history of racial problems, poverty, educational gaps, drug abuse, crime, etc., and while this DOESN’T mean that you won’t be safe at Hopkins (read here about JHU/Baltimore safety: http://talk.collegeconfidential.com/johns-hopkins-university/1821701-questions-about-baltimore.html#latest), it does mean you get nearly unparalleled opportunities for community outreach and truly making a difference while getting great educational experiences. I will admit though that Providence does also have a diverse population with crime, etc. (all on a much smaller scale, but they are there), so I’m sure Brown would offer you some of these experiences as well. I will also note that Brown just started their graduate school in Public Health and (while this is my opinion and general commentary) some avoid new schools since they are not established, not well-integrated and typically have to work out kinks in their curriculum, etc.
As for the concern for competition, of course the stereotype is Brown is laid-back and Hopkins is death, but is anything really that cut and dry? Do you really think the premeds at Brown are just smelling the roses and frolicking?That there is no stress to do well in Organic Chemistry and outperform their peers so that they can get into Brown School of Medicine? At the end of the day, this career path attracts hard-working, competitive students (NOT CUTTHROAT! There is a big difference!), and you will find them wherever you go. You can read by many posters on the JHU thread (both past and current students) that Hopkins is competitive (yes, everyone wants to do well! Gasp!), but has become a much more collaborative school across many of its disciplines. There has been a big push to greatly reduce the number of classes that have set grade quotas (“only 30% of the students at most can get A’s”) such that there are almost none of them in the Neuro program, and only a few premed courses while I was there (Orgo and Biochem, and hopefully this has changed). Curriculum that more heavily emphasizes team projects and group learning has probably had a big impact on whatever the environment may have been in the past. Also, the fact that it is a small school also makes people who initially think in terms of “me vs them” quickly either change their attitude or otherwise find themselves picked last for the proverbial kickball game.
I can also tell you that I have yet to meet anyone from Hopkins who went on to say that medical school was more difficult than their undergrad experience. I found comfort in knowing that the study skills and work ethic I developed at Hopkins would be a smooth transition into medical school (and it was), and my foundation let me succeed in med school while some of my peers had a rocky start. I will admit that Hopkins has a much higher per capita of premeds than Brown, which some people like and others don’t. Some people find comfort in the camaraderie and benefit from being around others who are in the same boat as them and doing the same things as them. Others think that it’s over-saturating and find it stressful. That just comes down to the person. Honestly, if you’re being stressed out from the people around you then I wouldn’t be blaming other students but would simply say you need to find avenues to relax and put things in perspective. But this is a valid complaint nonetheless. Overall though, the experience always depends on the person. I actively sought out study buddies and found a great group of premeds that worked together, discussed answers for hw, endured the MCATS etc. and never would have thought that I was at a school that was even considered to have a bad reputation.
Don’t pick Brown over Hopkins simply because everyone will tell you “Hopkins, isn’t that the diehard school?” and “Brown, oh, that’s the laid-back school.” Do more research and consider the points I’ve brought up. Overall, given what you want to study and your career interests I would choose Hopkins (but then again, this is the Hopkins thread, so what would you expect?).
