Gross anatomy for med students in college?

Hello, i want to pursue family doctor or pediatrician as a future career. I heard that you had to dissect a cadavar. My problem is i am anemic and often black out and faint when i see certain things. when i dissected a fetal pig in anatomy class i fainted. I was wondering if i fainted will i be disqualified from the class or would i have to redo the lab?
