AMSA is a student organization. The Pre-med committee is from the Pre-med department or Pre-Professional(premed,prelaw,etc.) department of your college and is run by the college and not the students.
Some schools do not have a pre-med department. Go to you biology department office or ask your advisor if there is a Pre-med/Pre-Professional Office.
Or you can tell us your school and we will set you on the path to righteousness.
Thanks.. I go to the University of Florida. I am not aware of a pre-med committee but i'll find out.
