What is the best college path to become a Pediatric Cardiologist?

Yes, but you’re saying you know little about it. You asked if it’s a career. Just about any actual research online will lead you to the who what and how.

Many don’t settle on a particular med path until in med school, doing student rounds, etc.

On your other thread, your grades and SAT are good not great and APs are not strong. You don’t mention AP sci or any math-sci grades. And the only health related is one stint as a hosp vol. How do you feel prepared for premed?

Im saying you have some work to do. Dreams are just step one.
