So, you are skipping one giant step, which is college. People don’t go straight into medical school from high school (though I know something like this is done in other countries where college level courses are combined with medical courses). If she is smart, and does well at a good college while majoring in a scientific discipline (like biology, chemistry, physics, math, biochemistry, molecular biology), then she should be able to get into medical school. Realize though that med school admissions are extremely competitive. Many people are turned away who want to go to medical school. And, it is no easy road, with long days and nights, hard classes, and enormous financial sacrifice (at least in the beginning).
