I was a terrible high school student, I had to repeat pre algebra, english 3, and even physics simply because my high school was a joke and didn't care.. after graduating, one of my parents pressured me into getting a community college technical degree, it was then I found out I wanted to pursue medicine. 4 years laters, I am not in medical school yet, but I am currently on my 4th interview(which is tomorrow). Doing well in high school can get you into a great college, but if not, I went to community college for 2 years, 3 years in state school, did well on the mcat, maintained a high GPA, and I am here, it won't matter how your high records are (unless you were in dual enrollment courses, but thats a whole other story). Good luck
