I need a nursing school

You need to research that yourself. There is no way anyone can tell you what schools you can get into. Is that a GPA for a bachelors degree or just random classes? You have a "chance" at any school you apply to. When your grades suck you are going to have to spread a WIDE application saturation and hope for the best. I will tell you this...with crappy grades all you are doing is hurting your odds of getting into school. Study more and get better grades. No excuses.

i have an overall gpa of 2.89 have not done all my pre-req sciences classes but just need 3 science classes left..please advice me on what universities i can apply for that i may have a chance to get into.

You haven't completed all the pre-requisite courses yet; "just 3 science classes" is A LOT to do still. Your GPA is pretty bad now; what do you believe is the likelihood of acing every one of the science classes to bring up that average?

Nursing programs will be very interested in the sciences, fyi, so....you will have to do very well to combat the rest if you want to stand a chance.

You can't apply until you have all that done, so it seems to me your current GPA isn't of much relevance. Let us know when you are completing the pre-requs, and know what your ready-to-apply-to-nursing GPA is then.
