Question: would an 80% average in high school get me to be a general practitioner (doctor) and going into university? 

Answer: 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.  \n\nYour 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.
