text: Take the MCAT's, do well on them (which you probably should.)  Apply to med school of your choice...go into serious debt.  Med school is 3 years, then you intern and have your residency (which I believe is another 3 years).  You then can practice in general medicine, if you specialize, that's another residency.  But yes, someone with a bachelor's in nursing can be a doctor, most med schools don't require a pre-med degree to apply and be accepted.  The requirements for acceptance would depend on the med schools you're applying to.  Best of luck to you.
