Chances for nursing + questions on acceptance into other majors

Hi!
I just applied for nursing and i was wondering if its a long shot for me?
GPA: 3.73
SAT: 1800 math:550 cr:630 writing:620
ECs: Big Sister mentoring, going to start peer mentoring during senior year with special needs students, student broadcasting, theater, and campus ministry
Do you think I have a shot for nursing? If I don’t get accepted to nursing would I still have a chance to get accepted to the university as undecided?
