The safer, easier, cheaper, more “civilized” lifestyle choice is to go to nursing school, with the eventual goal of nurse anesthetist or some other nurse practitioner level employment. BUT, do you have the kind, caring personality that is suited for nursing? Do you think that you would prefer to work more intimately with fewer patients, which is what nurses in training do? Nursing school will be far less rigorous, less intellectually challenging, and the path towards CRNA or NP will require literally 1/10th the training hours that med school and residency would require. It is a shorter pathway that is more easily followed, with a higher likelihood of achieving the final goal. Even if you don’t get into CRNA, there are so many things that a smart nurse can do. ICU nursing, teaching, corporate work, sales, become a NP. the list goes on and on.
To get into med school, you’d need to be a top student in highly competitive premed classes, plus your major, and achieve a high MCAT score, not to mention that med schools want to see research, clinical experience, and volunteer work. But at the end of 4 yrs of college, 4 yrs of high-intensity med school (the last two of which are clinical training that often requires 12 hour days, with about 1 in 4 nights working overnight), and 4 yrs of residency for anesthesia, again working at least 80 hours/week, you would be an anesthesiologist who would be the leader of the anesthesia team, likely supervising others, and you’d be qualified to do a fellowship in the really exciting, challenging sort of anesthesia, cases like cardiac procedures involving bypass, emergency trauma cases, the really tough stuff.
Your high school achievement and your SAT/ACT score offer some prediction of whether you will be able to achieve at the level required to gain admission to medical school. If you tended to be a top student in the most rigorous classes your high school offered, including AP sciences and AP math, and your SAT score was over 1500, your ACT was over 34, then you probably would be able to achieve the GPA and the MCAT score required to get into med school (with a LOT of very hard work). If you are an URM, you might be accepted with slightly lesser qualifications. There is less scholarship money available for med school than for undergrad - people are expected to take out massive loans. You might have to take on a lot of debt, and if you had to drop out before finishing med school AND residency, you’d find that amount of debt almost impossible to pay back. Most premeds wind up dropping premed, but most people who get into med school do wind up finishing, and also finish residency.
Only you know whether you’re up to the challenge of the med school path. However, with the financial future of medicine uncertain, unless you are absolutely driven to become a doctor, I’d say choose the nursing pathway instead.
I have no idea how the two schools would handle it if they were to find out that you sent deposits to two schools. I’d suggest that you make your decision quickly, and withdraw from one of them. Other commentators might know whether there is a risk of a school withdrawing its acceptance if they were to become aware that you were holding a spot at two schools.
