I was looking at a major that I'm interested in and in the description it said , that the major is a 5 year course. How would this affect me in AFROTC and trying to be a pilot? PLEASE HELP!!

Nothing directly, however you will compete a year after your peers who are doing 4-year degrees, IIRC. So instead of Year 3, you would get your slot in Year 4.

If you're on scholarship they'll continue to pay and you just need to complete the 5th year as an ROTC cadet still.

I was in a 5 year program at ERAU but myself and most of my classmates managed to complete in 4.5 and graduate in the fall.

Definitely not a deal breaker. Looking back on it i wish I stayed in college longer ;)

Just FYI i would say roughly 30-40% of the cadets at my det were on a 5 year track. I'm assuming you are a tech major which is no big deal, you would just be a super senior your 5th year and pretty much just sit back and help out with anything your POC/upperclassmen need until you commission.
