My Cousin Started Looking at Medical Schools Abroad

My cousin recently decided that she wants to become a doctor and has started exploring options outside her home country. Last weekend, she showed me several Med school in the Caribbean programs she had found online. We talked about tuition, accreditation, clinical rotations, student support, and what happens after graduation, but she still feels unsure about how to compare them. If anyone has gone through a similar decision, what did you focus on first? Were there any details you wish you had researched before applying?
