Definitely. As someone who’s gone through this meat grinder twice so far, I know they don’t care what your major iss so long as your grades* are solid (and MCATs are good). But that’s the short version.
They don’t just look at grades as an indication of ability/intelligence/responsibility/etc, it’s also a way to roughly assess your dedication to your interests, which in turn speaks for how dedicated you will be as a physician. Your numbers ultimately play an important role in demonstrating how well you’ll handle med school academically and in getting you an interview, which is a positively HUGE factor in a school’s decision to accept or not. They want to see that you have interests and a sincere desire to be a doctor and that your major, extracurriculars, etc. weren’t just a means to an end. Many applicants who majored in bio did that because they saw it as a route to medical school (but don’t rule out bio, by any means!). As Thing Fish said, that’s not the case. They look for people who are passionate about their interests (among which must be medicine, of course).
As for premed classes, to clarify IvoryTowerDenizen’s list, the most basic requirements are 2 semesters/1 year each of:
General chemistry
Gen chem lab
Organic chemistry
Orgo lab
General Physics
General Physics Lab
Biology
Biology lab
English/literature (definitely required)
Calculus (occasionally you’ll run across a school that doesn’t ask for this explicitly)
The biology requirement is very open-ended in that you can include any course from your school’s bio department, or a relevant course from another area (as a physical anthropology major, I could have conceivably used some of my classes there for the bio requirement). I wouldn’t include biochem or cell bio in this because more and more schools are adding separate requirements for those. Schools are NOT generous with letting a single course meet two requirements. For example, USC needs you to have taken a biochem as well as a molecular biology class. I had two bio courses, biochem, and I took cell bio for the molecular requirement (among other reasons).
Good grades in these areas as well as overall will show ability, and that will get an interview, but medical schools really want dedicated and compassionate people to train. Extracurriculars, community service, and maybe time spent shadowing a doctor will help demonstrate that, so it’s important that your daughter find an activity that means something to her too.
The bottom line is that it’s hard, hard work, but if you take satisfaction from it as an end unto itself, you’re on the right track. I hope this helps, but many, many books have been written about this subject, each with their own unique gem of advice. When your daughter starts school this fall, What the … !!!, she oughta check with the career services department to see what they offer premeds as far as advisors and mock interviews go.
And as a parting thought, don’t let that list of pre-reqs be discouraging. Assuming 9 credits a year needed to graduate, with 1 for every one-semester class, 2 for every full-year class, and 0.5 for a lab, that works out to 20 credits out of 36 for premed classes. That leaves plenty of room for completing a major as well as some exploration. If you help her space things out right, and it’s what she wants, it’s well within her grasp.
Hope this helps.
*I learned this the hard way. After two application years with only placing on alternate lists, the chickens clearly have come home to roost despite my MCAT score and experience
