BS Psych,
After reading all those posts I felt I HAD to reply.
I graduated more than 20 years ago with a BA in Psych and a GPA <3.0. I got a "D" in Biology and Finite Math, a "C" in statistics, a "C" in botany. Get the picture?
In the 90's I went back to school and hauled ass to do extremely well in my science prereqs. Then I applied, was accepted and completed, the Physician Assistant program at Duke. I am now returning to school again, to get a BSN/MSN (Midwifery). Before going to PA school I spent years in health care, experience helps!
Bottom line, what was is unchangeable. Move forward with NOW. We cannot change the past (boy did I ever wish I could retake Biology!!!), but we can learn from it and go forward. And don't spend a lot of time apologizing for your past grades- acknowledge them and, matter of factly, move on. Do you need to prove yourself? we all do!!

Then... you will either succeed at your presnet dream or perhaps something else will appear.
Enjoy!!!
