<human>: I'm just looking for a little guidance.  I'm 21 years old and until last year I didn't know what I wanted to do.  I went to engineering school, which is not a bad path for someone who doesn't know.  

However, I got 3/4ths of the way through the Civil Engineering program and decided definitively I want to be a doctor.  Specifically in the area of cardiology.  I did my research and know being a doctor today can be a nightmare with the liabilities and what used to be such a respected career is slowly becoming an ATM for people via malpractice suits. (just one side of it)

I know it's the right path for me, but I don't know the best way to go about it.

Can you succinctly summarize the text in 1-3 sentences?
<bot>: I'm a civil engineer with 1 year left of school, but I want to go to medical school.  How do I get there?
