The co-op at NU is for the engineering students. Science students would just have to find regular internships. A lot of them are premeds anyway so most of them are more interested in academic research instead of industry experience.
"The Georgia Tech Undergrad Co-op Program is a five-year, academic program designed to complement a student's formal education with paid practical work experience directly related to the student's academic major. It is available in all engineering majors, as well as in many majors in other colleges at Georgia Tech."
