Hi, I was wondering if anyone knows of I/O PhD programs that do not make you start over (ie add 5 years) after already completing a Master's. I'm currently an undergraduate student (3rd year) looking to apply to PhD programs for Fall 2013. However, I am curious to know in the event that I only get accepted to Master's programs, if I go for a PhD afterwards, will I have to add on an additional 5 years (I know some programs make you "start over")? If not, which schools let your finish it up after a Master's in ~3 years? Thanks!
