concerned about acceptance

i had another appointment with an advisor from OU today and after talking, i felt very discouraged. i am 47 with a previous BBA from OU, however, my college GPA was only a 2.86, so i have been working soooo hard to make As in all my science prereqs. even with a 4.0 in all the science courses, i can only raise my GPA to a little above a 3.0. i was hoping that maybe my age would make a little difference if they saw that the 2.8 was over 20 years ago, but my recent grades were much better, but she says they dont look at age. which means they wont know any of my history. i am just very discouraged that a 3.0 wont get me in. she said they had 400 applicants this jan. and only take about 120. i am applying to UCO, w hich is where i have taken my prereqs, and i am applying to rose state and probably oCCC. i was really wanting a BSN, so i could go on to NP, but i just dont know what to think. at 47, its not like i have several years to reapply. i am truly passionate about this career and have felt led this direction, but i am so frustrated, because there is only so much i can do about my GPA at this point.
