High school to Pathology

Hi, I'm a freshman in high school and I really want to be a pathologist in the long run. Without anyone to guide me, I would like to ask those who have the knowledge on how can I achieve this dream of mine (better if you are a pathologist). I have heard that getting great marks on Biology and Chemistry is a step to becoming a pathologist. I have an outstanding performance in school including Biology. I am taking Chemistry next year and psychology as my elective. I also volunteered in a hospital (I thought this would give me a start) Please give me more information. Do not comment if you do not have anything useful to say. Thank you.
