Why? If you intend to become a doctor, you will have four years of medical school followed by a 2-7 year or so residency…plus passing your board exams. And you won’t be able to attend law school while you are completing your doctor training.
And then you will have three years of law school…and you need to hope for some excellent internships while in law school…so it’s not like you can work part time as a doctor.
And if you don’t practice medicine for several years after residency, your skills will not be as sharp as they need to be.
I think you need to take your time and not rush through your schooling or career choices. My opinion.
