text: would an 80% average in high school get me to be a general practitioner (doctor) and going into university?   if you are in the united states, your high school gpa has nothing to do with your ability to become a physician.  it does effect your ability to get into a college or university that will help your chances of getting accepted into medical school.  medical school, as i understand it, is not as popular as it used to be, but can still be competitive to enter.    your best bet is to major in pre-med, biology, zoology, etc and buckly down to get the best grades you can and prepare for the mcat exam, which is a key factor in getting accepted into med school.  the college you attend can also be a factor in that a good gpa from a recognized school will be more competitive than from a tier 4 school, all other things being equal.  it also will prepare you better to succeed in med school.
