The relevance is that you’re set on a particular specialization without any clinical experience. Choosing to do a BS/MD instead of the usual path to medical school is also an act of early specialization. I wanted to understand how you make these decisions.
Thank you for sharing the personal relevance this specialty has to you. Given your lack of healthcare experience thus far, I’d say an early assurance program is a risky choice for you, but given your personal history that is informing that choice, it may still be the right choice for you.
The article I’m linking below lists all of the programs in the US, and I am sure you could qualify for at least some of them.
It also explores the pros and cons of these programs at length, and I encourage you to read it all with an open mind. In addition, one con that they leave unmentioned is that in committing early to a particular medical school you may miss out on admission to a better medical school that you could have earned via the traditional pre-med+MCAT track.
Weigh the cons carefully, and remember that there are some 23,000 cardiologists in the US. Not all of them got there through an early assurance program.
