Once training is completed, a forensic pathologist must pass an exam to become board certified.
To be totally honest, the vast majority of folks who go to med school often change their mind about what they want to sub specialize in, particularly once they start doing clinical rotations and get to experience firsthand what different types of doctors do, so the best strategy would probably be to focus on getting into a good undergraduate program and working hard to maintain a strong GPA (ideally 3.8 or higher) and lots of healthcare-related volunteer experience. As long as you have solid grades, have good volunteer/extracurricular experiences, and get a decent MCAT score (the MCAT is a standardized test that virtually all med schools require for admission, which most pre-med undergraduates take in their final year of college) then you should be able to get into a Medical School in the US.
You will then need residency and fellowship training (several more years) after graduation from Med School
So basically, it’s a long and challenging path but medicine (regardless of what sub-specialty) is very rewarding and has great job security so if you’re willing to work hard it’s a good choice.
