i'd say a little above average. there's room for improvement. if you have a field of study picked, make sure you get internships within that field while in college. grades are important for graduation, but experience is just as important for getting a job.
talk with your counselor, or a professor in that field of study, and ask about any relevant work internships you can do while in college. some colleges will use internships as college credit towards your degree, again, ask a counselor if such a program exists.
even if a internship job isn't a paying job, it'll help in the long run when you apply for a paying job, that you have the edge in terms of relevant work experience and education.
start asking around now to teachers in your field or a counselor. companies have different restrictions on who can apply and when for internships.
