Hi Kyla.
while I can't tell you your chances, as I don't know the averages with my group, there are a couple things I could say.
is the 3.25 your complete GPA, or is that the GPA from the 4 classes they look at? While there is a minimum GPA to apply, the only 4 classes that count towards your application score are Bio 101/101a, 102/102a, 103/103a and Biostat. (BST 322)
as for the TEAS exam. All I can say is: are you satisfied with that score? If you're satisfied, then leave it be. If you aren't satisfied and are able to afford another round, go for it.
