Background info: I'm a white Cuban from Alabama at Brown, majoring in Slavic Studies. I'm only going into sophomore year. I really want to go to a med school in the northeast, ideally continuing at Brown, and I want to avoid taking a gap year between college and med school for some personal reasons.
The shaky first semester: I only took three classes (the standard courseload at Brown is four) and took calculus pass/fail (S/NC), so I'm afraid that looks bad. I still have a 4.0 at the moment, though.
Grades: I've taken several premed STEM classes that are supposedly representative of the rest of the premed classes and got all As in them, and I feel pretty comfortable in saying that I can maintain a 3.85 or higher sGPA and 3.95 cGPA throughout college. I know this sounds cocky, but I have access to lots of tutoring because I'm a varsity athlete, my very helpful friends are good in the areas where I'm weakest, and I can get good study material through my teammates. Also, I plan to study abroad in Russia the summer between sophomore and junior year.
MCAT: I plan to take 5 classes per semester sophomore year so that I can take 3 classes junior spring and study for the MCAT. I plan to study at least 300 hours for the MCAT and am a generally good test taker, and I will be aiming for a score of 520 or higher. I plan to begin over winter break of my junior year, studying about 7 hours per day for the twenty-odd days after New Years and 10-12 hours per week (the same amount of time as the rest of my classes) all of spring semester. Is this a good study plan for the score I want, or should I space it out more/increase the hours?
ECs: I'm a varsity equestrian and I'm co-founding a club whose goal is to facilitate interesting, healthy philosophical debates that allow Brown students to develop their argumentative faculties and interpersonal skills. Since I only turned 18 after the fall semester of freshman year, I'm only now getting my EMT-B and I plan to volunteer for one shift per week for the rest of college (which would total 480-600 hours by the end of junior year). Now that I'll have a car on campus, I'm going to volunteer for ~3 hours per week for an equine therapy organization (will total about 200 hours by the end of junior year), also presumably for the rest of college. I have a research internship this summer at a PCR reagent company (and I worked for them in high school, too) and am planning to get a school-year position in a lab as well, though maybe not until junior year due to the fact that taking 5 classes per semester prohibits me from getting academic credit for working in a lab and credit positions are the only ones I've seen. I'm also independently working on publishing a linguistics paper. I'm struggling to get shadowing opportunities and it seems that 50 hours might be the best I would be able to do. Aside from more shadowing, how can I improve my ECs?
With my plan as it is now, where do I stand? What are my chances of getting into Alpert (I think the fact that I'm a non-STEM major, which I've heard they like, makes up for the fact that I go to Brown and they already have PLMEs)? Do I have any chance at all of getting into a T20? What about other schools in the northeast, like Dartmouth, Tufts, UConn, etc? Where are the biggest areas I need to improve? Thanks for the help!
