I've been working on pre-reqs for two years now (in my fourth semester). I've only applied to one nursing program in the fall, and believe me, I am terrified. I have a 4.0 GPA and an 87 on the TEAS, yet the program is very competitive.
I saw a Walt Disney quote on this site a few days a go, "Why worry? If you've done the very best you can, worrying won't make it any better", and I am trying to drill it into my brain. I won't hear anything until the end of May.
