I also started in the PT program. I experienced no prejudice (that I was aware of) during OCI. Pro-tip on the app: Don't check the PT/FT box. Just check the PT box. Make sure your PS drums up your work experience.
Just curious as to why one wouldn't check the PT/FT box. Wouldn't the app be viewed the same for both programs? Also, as a part time student, are classes limited to just the evenings? Or can you take daytime classes as well?
