I really think that the essay holds a lot of weight. I had an undergrad gpa of 3.8 and a 4.0 in all the prerequisites. I was currently in Chemistry when I submitted my application and registered for microbiology for summer session 1 (now completed). I felt really good about my essay which was pretty passionate and touched upon some personal experiences which guided me into the direction of nursing. I clearly remember them saying at the info session that the essay is so very important. Good luck to everyone wait listed or applying next year.
