I graduated from a large university one year ago with a bachelors degree. Today I was looking back on my computer at some of the old essays, and I released that I had "self plagiarized" on one occasion--I used sections from one of my essays I wrote from one class, and later used sections of that essay for a different class. At the time I didn't realize this probably isn't okay (I just assumed it was my own writing so I could use it how I want). Both essays were submitted on courseweb, and it was never caught by anyone. I checked my schools academic dishonesty policy and it does not mention "self plagiarism" as being an offense. However, I'm apprehensive that this might be found out in the future and I'll get in trouble. Should I be worried about this? Or is it not a big deal since it was my own thoughts/writing that was being reused?
