I see you already have BC on your list.
Just an FYI, you can do the required courses for medical school applicants at just bout every four year college (arts conservatories excluded). That being the case, if you really are interested in IB, you should concentrate your applications on schools that are good feeders for that.
Question…you say you don’t want to live someplace expensive like NY. Is that just for college, or are you hoping to find an IB job or something that is not located on a large city? I’m a little confused about that.
I’ll defer to @Catcherinthetoast to provide more info, but I’m concerned you won’t have time for internships related to IB (very important in terms of future work) and things like shadowing doctors, volunteering with needy populations, working in some kind of patient contact medical place, etc. Those last few things are expected of all medical school applicants.
How will you do this all?
